Instead of unconditionally expiring the timer and calling a long
mt_release_contacts(), we can check if some slots are used when the
timer expires.
We can also remove the timer if we happen to receive all the releases.
The logic behind the MT_IO_FLAGS_PENDING_SLOTS could be implemented by
counting how many slots are active, but using bits feels slightly more
efficient.

Instead of blindly trusting the hardware to send us release, we should
consider some events can get lost and release them when we judge time has
come.
The Windows 8 spec allows to be confident in the fact that the device
will continuously report events when a finger touches the surface.
This has been tested on the HID recording database I have, and all of
those devices behave properly.
Also, Arek tested it on his Lenovo Yoga 910, which exports such bug in
some situations, when the movements are rather slow.
We use an atomic bit here to guard against concurrent accesses to the mt
slots because both mt_process_mt_event() and mt_expired_timeout() are
called in interrupt context.

There are many situations where generic HID driver provides some basic level
of support for certain device, but later this support (usually by implementing
vendor-specific extensions of HID protocol) is extended and the support moved
over to a separate (usually per-vendor) specific driver.
This might bring a rather unpleasant suprise for users, as all of a sudden
there is a new config option they have to enable in order to get any support
for their device whatsoever, although previous kernel versions provided basic
support through the generic driver. Which is rightfully seen as a regression.
Fix this by including the entry for a particular device in
hid_have_special_driver[] iff the specific config option has been specified,
and let generic driver handle the device otherwise.
Also make the behavior of hid_scan_report() (where the same decision is being
taken on a per-report level) consistent.
While at it, reshuffle the hid_have_special_driver[] a bit to restore the
alphabetical ordering (first order by config option, and within those
sections order by VID).
This is considered a short-term solution, before generic way of giving
precedence to special drivers and falling back to generic driver is
figured out.
While at it, fixup a missing entry for GFRM driver; thanks to Hans de Geode for
spotting this (and for discovering a few issues in the conversion).

I was trying to understand this code while working on a warning
fix and the locking made no sense: spin_lock_irqsave() is pointless
when run inside of an interrupt handler or nested inside of another
spin_lock_irq() or spin_lock_irqsave().
Here it turned out that the comment above the function is wrong,
as both recv_ishtp_cl_msg_dma() and recv_ishtp_cl_msg() can in fact
be called from a work queue rather than an ISR, so we do have to
use the irqsave() version once.
This fixes the comments accordingly, removes the misleading 'dev_flags'
variable and modifies the inner spinlock to not use 'irqsave'.
No functional change is intended, this is just for readability and
it slightly simplifies the object code.

saw it in configurations that had neither SMP nor LOCKDEP enabled.
As we can see, we only enter the case if 'complete_rb' is non-NULL,
and then 'cl' is known to point to complete_rb->cl. Adding another
initialization to the same pointer is harmless here and makes it
clear to the compiler that the behavior is well-defined.

Generic battery handling code is spread between the pen and pad codepaths
since battery usages may appear in reports for either. This makes it
difficult to concisely see the logic involved. Since battery data is
not treated like other data (i.e., we report it through the power_supply
subsystem rather than through the input subsystem), it makes reasonable
sense to split the functionality out into its own functions.
This commit has the generic battery handling duplicate the same pattern
that is used by the pen, pad, and touch interfaces. A "mapping" function
is provided to set up the battery, an "event" function is provided to
update the battery data, and a "report" function is provided to notify
the power_supply subsystem after all the data has been read. We look at
the usage itself rather than its collection to determine if one of the
battery functions should handle it. Additionally, we unconditionally
call the "report" function since there is no particularly good way to
know if a report contained a battery usage; 'wacom_notify_battery()'
will filter out any duplicate updates, however.

At the moment, our driver relies on 'wacom_battery_get_property()' to
determine the most likely battery state (e.g charging, discharging, or
full) based on the information available. It is not always possible
for the function to properly determine this, however. For instance,
whenever an AES pen leaves proximity the battery state becomes
indeterminite. This commit adds the ability to provide it with explict
state information if desired. Whenever explicit state is not required
(the majority of circumstances), WACOM_POWER_SUPPLY_STATUS_AUTO can
be used in its place.

It apears that devices designed around Wacom's G11 chipset (e.g. Lenovo
ThinkPad Yoga 260, Lenovo ThinkPad X1 Yoga, Dell XPS 12 9250, Dell Venue
8 Pro 5855, etc.) suffer from a common issue in their HID descriptors.
The logical maximum is not updated for the "Contact Identifier" usage,
leaving it as just "1" despite these devices being capable of tracking
far more touches.
Commit 60a2218698 began ignoring usages with out-of-range values,
causing problems for devices based on this chipset. Touches after
the first will have an out-of-range Contact Identifier, and ignoring
that usage will cause the kernel to incorrectly slot each finger's
events (along with all the knock-on userspace effects that entails).
This commit checks for these buggy descriptors and updates the maximum
where required. Prior chipsets have used "255" as the maximum (and the
G11, at least, doesn't seem to actually use IDs outside the range of
1..CONTACTMAX) so continue using this value.

Because HID_DG_TOOLSERIALNUMBER doesn't first cast the value recieved from HID
to an unsigned type, sign-extension rules can cause the value of
wacom_wac->serial[0] to inadvertently wind up with all 32 of its highest bits
set if the highest bit of "value" was set.
This can cause problems for Tablet PC devices which use AES sensors and the
xf86-input-wacom userspace driver. It is not uncommon for AES sensors to send a
serial number of '0' while the pen is entering or leaving proximity. The
xf86-input-wacom driver ignores events with a serial number of '0' since it
cannot match them up to an in-use tool. To ensure the xf86-input-wacom driver
does not ignore the final out-of-proximity event, the kernel does not send
MSC_SERIAL events when the value of wacom_wac->serial[0] is '0'. If the highest
bit of HID_DG_TOOLSERIALNUMBER is set by an in-prox pen which later leaves
proximity and sends a '0' for HID_DG_TOOLSERIALNUMBER, then only the lowest 32
bits of wacom_wac->serial[0] are actually cleared, causing the kernel to send
an MSC_SERIAL event. Since the 'input_event' function takes an 'int' as
argument, only those lowest (now-cleared) 32 bits of wacom_wac->serial[0] are
sent to userspace, causing xf86-input-wacom to ignore the event. If the event
was the final out-of-prox event, then xf86-input-wacom may remain in a state
where it believes the pen is in proximity and refuses to allow other devices
under its control (e.g. the touchscreen) to move the cursor.
It should be noted that EMR devices and devices which use both the
HID_DG_TOOLSERIALNUMBER and WACOM_HID_WD_SERIALHI usages (in that order) would
be immune to this issue. It appears only AES devices are affected.

The latest USB keyboards shipped on several ASUS laptop models
(including ROG laptop models such as GL702VMK) have the keyboards
backlight controlled by the keyboard firmware.
The firmware implements at least 3 different commands:
- Init command (to use when the system starts)
- Configuration command (to get keyboard status/information)
- Backlight level control (to change the level of the keyboard light)
With this patch we create the usual 'asus::kbd_backlight' led class

Keyboards handled by hid-asus declare special key functions

In addition, for the I2C keyboard volume controls are
separately declared in a Consumer Usage page, with the same
dummy usage problem.
The fix in 1989dada7c ("HID: input: ignore System Control

the problem described above, therefore dummy usages need to
be ignored in the driver itself.

The DS4 in BT mode sends initial input reports through report 1, which
is described in the HID report descriptors. When activated after sending
a certain feature report, the device uses report 17.
Currently the hid-sony driver fixes up the BT HID report descriptors,
so the HID layer can manage input reports for report 17.
We think it is best to eliminate this fixup and do the handling ourselves,
which is what this patch does. The main motivation is that there are
various users of DS4 through hidraw, including various cross-platform
applications/games, which have their own HID parsing across Linux/Win/OSX.
Due to the fixup the descriptors differ, which is causing pain for many
developers including major game publishers (who reached out privately).

working on Wine, which provides HID support now. Overall it felt

to non-existing axes in between ABS_MISC and ABS_MT_SLOT, because
the device already exhausted ABS_X-ABS_RZ. For a part the mapping
by hid-core is accomplished by a fixup in hid-sony as the motion
axes actually use vendor specific usage pages.
This patch makes the DS4 use a separate input device for the motion
sensors and reports acceleration data through ABS_X-ABS_Z and
gyroscope data through ABS_RX-ABS_RZ. In addition it extends the
event spec to allow gyroscope data through ABS_RX-ABS_RZ when
INPUT_PROP_ACCELEROMETER is set. This change was suggested by
Peter Hutterer during a discussion on linux-input.

The Accutouch 2216 is reporting BTN_LEFT/BTN_MOUSE rather than BTM_TOUCH
in it's capabilities, which is what user space expects a touchscreen
device to report. This is causing udev to consider the device to be a
"VMware's USB mouse" rather than as a touchscreen, which results in a
mouse cursor being displayed in Weston.
This patch adds a special driver for the device to correct the

It looks like a bunch of devices do not like to be polled
for their reports at init time. When you look into the details,
it seems that for those that are requiring the quirk
HID_QUIRK_NO_INIT_REPORTS, the driver fails to retrieve part
of the features/inputs while others (more generic) work.
IMO, it should be acceptable to remove the need for the quirk
in the general case. On the small amount of cases where
we actually need to read the current values, the driver
in charge (hid-mt or wacom) already retrieves the features
manually.
There are 2 cases where we might need to retrieve the reports at
init:
1. hiddev devices with specific use-space tool
2. a device that would require the driver to fetch a specific
feature/input at plug
For case 2, I have seen this a few time on hid-multitouch. It
is solved in hid-multitouch directly by fetching the feature.
I hope it won't be too common and this can be solved on a per-case
basis (crossing fingers).
For case 1, we moved the implementation of HID_QUIRK_NO_INIT_REPORTS
in hiddev. When somebody starts calling ioctls that needs an initial
update, the hiddev device will fetch the initial state of the reports
to mimic the current behavior. This adds a small amount of time during
the first HIDIOCGUSAGE(S), but it should be acceptable in
most cases. To keep the currently known broken devices, we have to
keep around HID_QUIRK_NO_INIT_REPORTS, but the scope will only be
for hiddev.
Note that I don't think hidraw would be affected and I checked that
the FF drivers that need to interact with the report fields are all
using output reports, which are not initialized by
usbhid_init_reports().
NO_INIT_INPUT_REPORTS is then replaced by HID_QUIRK_NO_INIT_REPORTS:
there is no point keeping it for just one device.

This patch fixes an issue in drivers/hid/hid-input.c where values
outside of the logical range are not clamped when "null state" bit of
the input control is not set.
This was discussed on the lists [1] and this change stems from the fact
due to the ambiguity of the HID specification it might be appropriate to
follow Microsoft's own interpretation of the specification. As noted in
Microsoft's documentation [2] in the section titled "Required HID usages
for digitizers" it is noted that values reported outside the logical
range "will be considered as invalid data and the value will be changed
to the nearest boundary value (logical min/max)."
This patch fixes an issue where the (1292:4745) Innomedia INNEX
GENESIS/ATARI reports out of range values for its X and Y axis of the
DPad which, due to the null state bit being unset, are forwarded to
userspace as is. Now these values will get clamped to the logical range
before being forwarded to userspace. This device was also used to test
this patch.
This patch expands on commit 3f3752705d ("HID: reject input outside
logical range only if null state is set").

Quoting from Jonathan Clarke in previous thread(2017/01/24):
"This division by 2 was added along with the touch width/height fields 6 years
ago so that those fields 'match the visual scale of the touch' for a specific
device (3M PCT)" "The scaling is also discarding information about touch size
(1 bit for each of width/height) which is useful for any application that wants
to know about it."
Jonathan mentioned just what I thought in a new project recently. It dosen't
make sense to discard 1 bit width/height in general case according to the spec
in multi-touch-protocol.txt so I would like to make a slight change here.
A quirk MT_QUIRK_TOUCH_SIZE_SCALING was added to service devices like 3M PCT
with a special visual scale and the division by 2 only take effect with devices
like that.

reporting of the events by hid-multitouch given that hid-input ignores constant
fields.
The autodetection is simply worked around by manually adding the device to
hid_have_special_driver[].
The processing of the events requires either a report fixup, or some specific
case handling. Given that the report fixup would require to basically rewrite
all the report descriptor, I went for the programatic way of fixing that after
the report descriptors are loaded.

Commit 025bcc1 performed cleanup work on the 'wacom_pl_irq' function, making
it follow the standards used in the rest of the codebase. The change
unintiontionally allowed the function to send input events from reports
that are not marked as being in prox. This can cause problems as the
report values for X, Y, etc. are not guaranteed to be correct. In
particular, occasionally the tablet will send a report with these values
set to zero. If such a report is received it can caus an unexpected jump
in the XY position.
This patch surrounds more of the processing code with a proximity check,
preventing these zeroed reports from overwriting the current state. To
be safe, only the tool type and ABS_MISC events should be reported when
the pen is marked as being out of prox.

In addition to its USB interface, the second-generation Intuos Pro
includes a Bluetooth radio that offers two pairing interfaces: classic
and low-energy. The classic interface functions just like the earlier
Bluetooth-enabled Intuos4 and Graphire4 tablets, appearing as a HID device
that our driver can work with. The low-energy interface is intented to
be used by userspace applications that make use of its paper-to-digital
capabilities.
Despite the USB interface using Wacom's new vendor-defined HID usages,
the Bluetooth interface provides us with useless black-box "blob"
report descriptors like past devices. We thus have to explicitly add
support for the PIDs and reports used.
These devices pack a /lot/ of information into a single Bluetooth
input report. Each report contains up to seven snapshots of the pen
state, four snapshots of the touch state (of five touches each), pad

The Intuos Pro seems to not like when we set the features right after
being powered up. Instead of waiting during probe, we can schedule the
switch mode and LED control in a deferred worker so that we don't have the
5 secs of delay from USB when the device is not accessible.
The USB timeout delays were really a pain because if you happen to unplug
the tablet while it is still waiting, you are just adding 5 second timeouts
to the USB stack. Which means that a new plug of the same tablet will also
gets delayed, and will also attempt to access the hardware while in
.probe(). So the tablet doesn't appear in the dmesg, the user unplug/replug
it to make it appearing... and so on so forth.
Really, this is for the best :)

When the LED class gets removed, it actually tries to reset the LED.
However, the device being disconnected, the set_report fails.
Previously, the attempt to cut lose this last event was through unsetting

Commit 345857b ("HID: wacom: generic: Add support for sensor offsets") included
a change to the operation and location of the call to 'wacom_add_shared_data'
in 'wacom_parse_and_register'. The modifications included moving it higher up
so that it would occur before the call to 'wacom_retrieve_hid_descriptor'. This
was done to prevent a crash that would have occured when the report containing
tablet offsets was fed into the driver with 'wacom_hid_report_raw_event'
(specifically: the various 'wacom_wac_*_report' functions were written with the
assumption that they would only be called once tablet setup had completed;
'wacom_wac_pen_report' in particular dereferences 'shared' which wasn't yet
allocated).
Moving the call to 'wacom_add_shared_data' effectively prevented the crash but
also broke the sibiling detection code which assumes that the HID descriptor
has been read and the various device_type flags set.
To fix this situation, we restore the original 'wacom_add_shared_data'
operation and location and instead implement an alternative change that can
also prevent the crash. Specifically, we notice that the report functions
mentioned above expect to be called only for input reports. By adding a check,
we can prevent feature reports (such as the offset report) from
causing trouble.

Support for the Asus Touchpad was recently added. It turns out this
device can fail initialisation (and become unusable) when the RESET
command is sent too soon after the POWER ON command.
Unfortunately the i2c-hid specification does not specify the need for
a delay between these two commands. But it was discovered the Windows
driver has a 1ms delay.
As a result, this patch modifies the i2c-hid module to add a sleep
inbetween the POWER ON and RESET commands which lasts between 1ms and 5ms.

The HID report buffers that are initially allocated on i2c_hid_probe()
might not be big enough to hold the HID reports from a specific device,
in which case they will be freed and new ones will be allocated in
i2c_hid_start(), at point which the device's report size is known. But
at this point ihid->irq is already running, and may call
i2c_hid_get_input() which passes ihid->inbuf to i2c_master_recv(). Since
this handler runs in a separate thread, ihid->inbuf may be freed at this
very moment, and i2c_master_recv() will write on memory which may be
already owned by a different part of the kernel, corrupting its data.
This problem has been observed on an Asus UX360UA laptop which has an
I2C touchpad, and results in a complete system freeze or an unusable
slowness with a lof of "BUG: unable to handle kernel paging request at
<address>" warnings. Enabling SLUB debugging shows a use-after-free
warning on memory allocated in i2c_hid_alloc_buffers() and freed in

https://bugzilla.kernel.org/show_bug.cgi?id=120181
The issue is in relation to an Asus touchpad device which currently does not
have multitouch support.
The device currently falls through to the hid-generic driver which
treats the device as a mouse.
This patch aims to add the multitouch support.

The DS4 side of hid-sony used the hid-core layer to assign buttons
and axes based on the HID report descriptors. The default mapping
was strange e.g. right stick using ABS_Z/ABS_RZ or the physical
'south button' being reported as BTN_EAST etcetera.
This patch makes the DS4 side ofi the hid-sony driver comply to
the Linux game controller spec as suggested in a discussion with
Dmitry on the linux-input list.
Currently the main user of the DS4 is the SDL2 library, which has
a mapping table using vendor/device/version as a key. In order to
not break SDL2 we discussed adjusting the version number, so it
can have both mappings. This was discust on linux-input and we
discussed privately with SDL2 developers.

The dualshock 4 supports both analog sticks of which one uses
ABS_X/_Y and a touchpad. In a recent discussion with Dmitry about
some input-mt changes we proposed for disabling pointer emulation from
input_mt_sync_frame, Dmitry mentioned ABS_X/_Y should report the
same data as ABS_MT_POSITION_X/_Y. The current driver is mixing axes
for different subdevices. It was suggested to make the touchpad
its own sub-device.
This patch turns the touchpad into its own device. In addition
this patch also moves the button underneath the touchpad into
the new device. It felt like this button should be part of the
device. No known user space application (not even SDL2) seems to
be using it.

A previous patch moved most input initialization from sony_probe to
sony_input_configured to avoid some race conditions. The driver has some
special logic to prevent the device to get registered twice in case the
user connects it both over Bluetooth and USB. When this condition
happens sony_input_configured returns a failure, but sony_probe continues
as hid_hw_start doesn't fail. As was discussed on linux-input, it is
acceptable for this function to fail.
This patch adds a check for the HID_CLAIMED_INPUT flag within sony_probe
to determine whether initialization succeeded correctly. The flag is
not set by the HID layer when sony_input_configured fails.

The purpose of HID_QUIRK_MULTI_INPUT is to have an input device per
report id. This is useful when the HID device presents several HID
collections of different device types.
The current implementation of hid-input creates one input node per id per
type (input or output). This is problematic for the LEDs of a keyboard as
they are often set through an output report. The current code creates
one input node with all the keyboard keys, and one other with only the
LEDs.
To solve this, we use a two-passes way:
- first, we initialize all input nodes and associate one per report id
- then, we register all the input nodes

When user tried to read some fields like hysteresis from IIO sysfs on some

sensor_hub_get_feature() copies the single byte from the report to the
caller buffer and returns "1" as the number of bytes copied. So caller
can use the return value.

The eraser end of the 8K pen available for the MobileStudio Pro has a tool
ID of 0x84a. The 'wacom_intuos_get_tool_type' function does not currently
recognize this ID, causing it to return BTN_TOOL_PEN rather than
BTN_TOOL_RUBBER. This does not cause a problem for the MobileStudio Pro
since, as a HID_GENERIC device, the driver relies on the state of the

User is unable to access to input-X-yyy and feature-X-yyy where
X is a hex value and more than 9 (e.g. input-a-yyy, feature-b-yyy) in HID
sensor custom sysfs interface.
This is because when creating the attribute, the attribute index is
written to using %x (hex). However, when reading and writing values into
the attribute, the attribute index is scanned using %d (decimal). Hence,
user is unable to access to attributes with index in hex values
(e.g. 'a', 'b', 'c') but able to access to attributes with index in
decimal values (e.g. 1, 2, 3,..).
This fix will change input-%d-%x-%s and feature-%d-%x-%s to input-%x-%x-%s

When report count is more than one and report size is not 4 bytes, then we
need some packing into result buffer from the caller of function
sensor_hub_get_feature.
By default the value extracted from a field is 4 bytes from hid core
(using hid_hw_request(hsdev->hdev, report, HID_REQ_GET_REPORT)), even
if report size if less than 4 byte. So when we copy data to user buffer in
sensor_hub_get_feature, we need to only copy report size bytes even
when report count is more than 1. This is
not an issue for most of the sensor hub fields as report count will be 1
where we already copy only report size bytes, but some string fields
like description, it is a problem as the report count will be more than 1.
For example:
Field(6)
Physical(Sensor.OtherCustom)
Application(Sensor.Sensor)
Usage(11)
Sensor.0306
Sensor.0306
Sensor.0306
Sensor.0306
Sensor.0306
Sensor.0306
Sensor.0306
Sensor.0306
Sensor.0306
Sensor.0306
Sensor.0306
Report Size(16)
Report Count(11)
Here since the report size is 2 bytes, we will have 2 additional bytes of
0s copied into user buffer, if we directly copy to user buffer from
report->field[]->value
This change will copy report size bytes into the buffer of caller for each
usage report->field[]->value. So for example without this change, the
data displayed for a custom sensor field "sensor-model":
76 00 101 00 110 00 111 00 118 00 111
(truncated to report count of 11)

The "Steering" usage (HID_UP_SIMULATION | 0xc8) is defined in HUT 1.12 as
follows:
"A steering wheel is a single degree-of-freedom device that rotates about
an axis. The zero position is always the neutral or 'straight ahead'
position, with positive values turning clockwise and negative values
turning counterclockwise. If the Coordinate Values Wrap attribute is
set, the steering wheel can be turned past 360 degrees."
The hidinput_configure_usage function canonically maps this usage to the
ABS_WHEEL axis, but hidinput_calc_abs_res does not recognize this axis
as one for which it can calculate a resolution. This effectively prevents
wheels from being assigned a proper resolution that userspace can use
to determine the precise angle of input.

Many of Wacom's display tablets include an "outbound" area where pen
digitizing is possible but outside of the display area. To ensure that
pen coordinates are mapped to the correct on-screen location, the driver
sets the minimum and maximum axis values of X and Y to those coordinates
which coincide with the screen edge. These values are simply the
hardware minimum/maximum plus/minus the outbound size for a particular
edge.
When outbound support was added/updated in ac414da, fa77034, and
ecd618d, we decided to have the wacom_features structs store the desired
minimum and maximum values directly. In hindsight, this was perhaps not
the best choice since it has allowed minor errors to crop up unnoticed.
Some tablets have had their coordinates over-corrected (e.g. most of the
devices "fixed" in ecd618d were already adjusted in ac414da), while
others never had a correction applied (e.g. the ISDv5 325, whose
declared maximum the hardware maximum instead of the outbound maximum).
A less error-prone method of handling the outbound is to let the driver
calculate the correct minimum/maximum values by providing it with both
the actual hardware maximums and the size of the outbound on each edge.
These values are more easy to verify as correct since the values can be
trivially compared against specifications.
This patch reverts the declared maximum values to the actual hardware
maximums, e.g. as declared prior to ac414da (values for these and other
display tablets that were subsuquently introduced have been verified
against specs). Per-edge outbound sizes are stored in the wacom_features
struct as offset_{left,right,top,bottom} and used in combination with
the hardware ranges to calculate effective axis ranges for ABS_X and
ABS_Y.

Wacom's professional tablets beginning with the Intuos4 are capable of
reporting an intermediate degree of proximity where the pen is no longer
close enough to communicate with ("in prox"), but still close enough to
be sensed ("in range"). This additional state is particularly useful for
performing palm rejection as it allows the driver to disable the touch
sensor while the pen is a greater distance from the tablet.
Like other professional tablets, the new MobileStudio Pro also reports
this intermeidate "in range" proximity state. Its descriptor assigns
usage 0xff0d0036 to this bit. Normally 'wacom_equivalent_usage' would
translate this to the standard HID "Quality" usage, but since this has
a different meaning we have it explicitly ignore the usage and define
it ourselves as "Sense" (since "In Range" is already defined by the
HID standard and interpreted by our driver as meaning "in prox").

Wacom's new "MobileStudio Pro" tablets are the first devices in their
branded product line-up to include a usable HID descriptor for the pen
interface. Like prior branded products, the device can operate in one
of two modes: 'Standard HID', and 'Wacom Custom HID'. Although the
first mode is usable by the HID_GENERIC codepath as-is (huzzah!), it is
subject to some restrictions -- most notably pressure being limited
to 2048 levels instead of 8192. To ensure tablets that include support
for Custom HID mode work optimally, we add support for its usages and
switch the device to Custom HID mode if possible.
The usages defined for Custom HID mode are often numerically similar to
their standard HID equivalents, allowing us to write a simple translation
function that takes arbitrary HID usages as input and which returns
the corresponding standard HID usage as output (if one exists). Switching
on this translated usage instead of the actual usage allows the existing
cases to apply to both modes of operation without having to explicitly
define every Custom HID usage.

The HID standard defines usages that allow digitizers to report the pen's
height, tilt, and rotation and which are used by Wacom's new "MobileStudio
Pro" devices.
Note that 'hidinput_calc_abs_res' expects ABS_Z (historically used by our
driver to report twist) to have linear units. To ensure it calculates a
resolution with the actually-angular units provided in the HID descriptor
we nedd to lie and tell it we're calculating it for the (rotational) ABS_RZ
axis instead.

The product name received from the string descriptor in the new MobileStudio
Pro line of tablets begins with "Wacom", which leads to unnecessary visual
noise in the device name when appended to the vendor name which also includes
"Wacom". Look for and fix cases like this.
