Recent kernels allow the generic-hid driver to be used as fallback for
devices with a specialized driver, when the hiddev is not listed in
hid_have_special_driver. Over time we are removing more and more
devices from the hid_have_special_driver table as devices get tested
to support this setup.
Before this commit the following happens when a HID device which has a
special-driver and is no longer listed in hid_have_special_driver, gets
enumerated:
1) device_add() gets called
2) bus_add_device() looks for a matching already registered hid driver,
and bind hid-generic to the new device
3) kobject_uevent(&dev->kobj, KOBJ_ADD) gets called notifying userspace of
the new hid_dev. udev calls modprobe based on the modalias in the uevent
4) The special driver gets loaded by modprobe
5) __hid_bus_reprobe_drivers() unbinds hid-generic and binds the new driver
There are a couple of downsides to this:
a) The probing messages printend when a HID driver bounds show up twice in
dmesg, which is confusing for the user
b) The (un)binding typically causes one or more evdev device-nodes to get
(un)registered firing of udev events to which e.g. the xserver responds by
(un)registering xinput devices and reporting this to interested clients.
IOW the i. bind generic, ii. unbind generic, iii. bind special driver dance
sets in motion a whole chain of events each step, while we really only want
the events from step iii. to be reported to userspace.
This commits introduces a request_module call before the device_add()
call, so that the special-driver is loaded when step 2) looks for a
matching driver and we directly bind the specialized driver.
Note the request_module call translates to an execve("/sbin/modprobe", ...)
and we now do this for each HID device added. So this is not entirely free,
but adding HID devices is not something which happens 100s of times a
second, so this should be fine.

As seen on some USB wireless keyboards manufactured by Primax, the HID
parser was using some assumptions that are not always true. In this case
it's s the fact that, inside the scope of a main item, an Usage Page
will always precede an Usage.
The spec is not pretty clear as 6.2.2.7 states "Any usage that follows
is interpreted as a Usage ID and concatenated with the Usage Page".
While 6.2.2.8 states "When the parser encounters a main item it
concatenates the last declared Usage Page with a Usage to form a
complete usage value." Being somewhat contradictory it was decided to
match Window's implementation, which follows 6.2.2.8.
In summary, the patch moves the Usage Page concatenation from the local
item parsing function to the main item parsing function.

According to hidpp20_batterylevel_get_battery_info my Logitech K270
keyboard reports only 2 battery levels. This matches with what I've seen
after testing with batteries at varying level of fullness, it always
reports either 5% or 30%.
Windows reports "battery good" for the 30% level. I've captured an USB
trace of Windows reading the battery and it is getting the same info
as the Linux hidpp code gets.
Now that Linux handles these devices as hidpp devices, it reports the
battery as being low as it treats anything under 31% as low, this leads
to the user constantly getting a "Keyboard battery is low" warning from
GNOME3, which is very annoying.
This commit fixes this by changing the low threshold to anything under
30%, which I assume is what Windows does.

Currently we depend on the guid check in ishtp_cl_driver.probe to match
the device and driver. However Linux device core first calls the match()
callback to decide the matching of driver and device, and then does some
preparation before calling the driver probe function. If we return error
in the driver probe, it needs to tear down all the preparation work and
retry with next driver.
Adding the match callback can avoid the unnecessary entry into unmatched
driver probe function for ishtp clients reported by FW.

When using this driver with the wireless dongle and some usermode
program that monitors every input device (acpid, for example), while
another usermode client opens and closes the low-level device
repeadedly, the system eventually deadlocks.
The reason is that steam_input_register_device() must not be called with
the mutex held, because the input subsystem has its own synchronization
that clashes with this one: it is possible that steam_input_open() is
called before input_register_device() returns, and since
steam_input_open() needs to lock the mutex, it deadlocks.
However we must hold the mutex when calling any function that sends
commands to the controller. If not, random commands end up falling fail.

Newer UC-Logic tablets, such as ones made by Huion have stopped
reporting in-range state, but they're otherwise worthy tablets. The
manufacturer was notified of the problem and promised to fix this in the
future. Meanwhile, detect pen coming in range, and emulate the reports
to the userspace, to make the tablets useable.

Currently we are using one additional static variable and a spinlock to
prevent contention of writing IPC messages to ISH hardware, which is
not necessary. Once ISH is ready to accept new data, we can push new
data to hardware. This pushing of new data is already protected by
wr_processing_spinlock for contention, which is enough. So use this
spinlock to check both readiness for accepting new data and once ready
allow writing of ipc message from queue to ISH hardware.
While here, cleaned up some space after return.

When performing a warm reset in ishtp bus driver, the ishtp_cl_device
will not be removed, its fw_client still points to the already freed
ishtp_device.fw_clients array.
Later after driver finishing ishtp client enumeration, this dangling
pointer may cause driver to bind the wrong ishtp_cl_device to the new
client, causing wrong callback to be called for messages intended for
the new client.
This helps in development of firmware where frequent switching of
firmwares is required without Linux reboot.

The bluetooth-keyboard which comes with the Toshiba WT10A tablet uses
a couple of usage codes in the vendor specific ffbc page.
The keyboard has a vendor-id of 04f2 which maps to Chicony.
Other then adding a few keymappings for the ffbc usages, no special
handling is necessary. So rather then adding a new hid-toshiba driver,
this commit adds the ID and 2 extra key-mappings to the hid-topseed
driver. The hid-topseed driver already contains mapping for some
ffbc usages (and does nothing else) and it already binds to another
Chicony manufactured keyboard.

The Intel ISH HID can now have other devices attached to it, not just
sensors. Hence ISH HID transport is no longer just used for sensors.
Currently the vendor and product id is hardcoded for sensors, but they
can be obtained from ISH firmware for the real device. The driver already
extract them and store as part of device_info structure in client_data.
So use vendor id/product id obtained from the ISH firmware.

Ring buffer implementation in hid_debug_event() and hid_debug_events_read()
is strange allowing lost or corrupted data. After commit 717adfdaf1
("HID: debug: check length before copy_to_user()") it is possible to enter
an infinite loop in hid_debug_events_read() by providing 0 as count, this
locks up a system. Fix this by rewriting the ring buffer implementation
with kfifo and simplify the code.
This fixes CVE-2019-3819.

Host driver should handle interrupt mask register earlier than wake up ish FW
else there will be conditions when FW interrupt comes, host PIMR register still
not set ready, so move the interrupt mask setting before ish_wakeup.
Clear PISR busy_clear bit in ish_irq_handler. If not clear, there will be
conditions host driver received a busy_clear interrupt (before the busy_clear
mask bit is ready), it will return IRQ_NONE after check_generated_interrupt,
the interrupt will never be cleared, causing the DEVICE not sending following
IRQ.
Since PISR clear should not be called for the CHV device we do this change.
After the change, both ISH2HOST interrupt and busy_clear interrupt will be
considered as interrupt from ISH, busy_clear interrupt will return IRQ_HANDLED
from IPC_IS_BUSY check.

While using Elan touchpads, the message floods:
[ 136.138487] i2c_hid i2c-DELL08D6:00: i2c_hid_get_input: incomplete report (14/65535)
Though the message flood is annoying, the device it self works without
any issue. I suspect that the device in question takes too much time to
pull the IRQ back to high after I2C host has done reading its data.
Since the host receives all useful data, let's ignore the input report
when there's no data.
