Jason Gerecke 5866d9e3b7 Input: wacom - use full 32-bit HID Usage value in switch statement
A HID Usage is a 32-bit value: an upper 16-bit "page" and a lower 16-bit
ID. While the two halves are normally reported seperately, only the
combination uniquely idenfifes a particular HID Usage.

The existing code performs the comparison in two steps, first performing a
switch on the ID and then verifying the page within each case. While this
works fine, it is very akward to handle two Usages that share a single ID,
such as HID_USAGE_PRESSURE and HID_USAGE_X because the case statement can
only have a single identifier.

To work around this, we now check the full 32-bit HID Usage directly rather
than first checking the ID and then the page.  This allows the switch
statement to have distinct cases for e.g. HID_USAGE_PRESSURE and
HID_USAGE_X.

Alexey Khoroshilov 1f906f8376 Input: gtco - fix usb_dev leak
There is usb_get_dev() in gtco_probe(), but there is no usb_put_dev()
anywhere in the driver.

As pointed out by Dmitry Torokhov:
The lifetime of gtco structure is already directly tied to lifetime of
usb_dev: when destroying usb_dev driver core will call remove() function
of currently bound driver (in our case gtco) which will destroy gtco
memory. Taking additional reference is not needed here.

Jason Gerecke 4eb1830b49 Input: wacom - send proper tablet state info when pen leaves proximity
The EMR sensor of Intuos4 and newer devices can send a packet with
0x20 in its second byte which contains only location information.
This packet is sent when the pen is too far away to reliably obtain
other information. Because only the location is updated userspace
will continue to see stale information for other values, most notably
TOUCH, PRESSURE, and DISTANCE.

This patch ensures userspace is not left with stale device state
information when the pen re-enters proximity (possibly leading to
the assumption the pen is still in contact even though it is
actually hovering).

Ping Cheng 8c0e0a4fa8 Input: wacom - prepare for syncing with input-mt changes
Henrik added new MT routines in release 3.7. This patch is to prepare
for the use of new MT routines.

In the newly added wacom_abs_set_axis() function, the first
if-statement assigns ABS_X/Y for number of contacts less or equal
to 2. So, it is single and 2 finger touch devices. Two finger touch
devices are processed here since they will not use the updated
input_mt_init_slots(), which does not offer benefit to those devices.

input_mt_init_slots() will take care of ABS_X/Y assignment when flags
are not zero. All touch devices with more than two contacts will use
input_mt_init_slots() with non-zero flags.

The second if-statement is for all MT devices, which include two
finger touch devices.

Jason Gerecke aea2bf6a57 Input: wacom - handle split-sensor devices with internal hubs
Like our other pen-and-touch products, the Cintiq 24HD touch needs data
to be shared between its two sensors to facilitate proximity-based palm
rejection.

Unlike other tablets that report sensor data through separate interfaces
of the same USB device, the Cintiq 24HD touch has separate USB devices
that are connected to an internal USB hub.

This patch makes it possible to designate the USB VID/PID of the other
device so that the two may share data.  To ensure we don't accidentally
link to a sensor from a physically separate device (if several have been
plugged in), we limit the search to siblings (i.e., devices directly
connected to the same hub).

Jason Gerecke 115d5e12a7 Input: wacom - introduce wacom_fix_phy_from_hid
The Cintiq 24HD touch cannot use wacom_set_phy_from_res to determine
the physical size of the touch sensor since the pen and touch are
on separate USB devices. The physical size is, however, provided in
the HID descriptor, just scaled to a unit we don't use.

This patch introduces the function wacom_fix_phy_from_hid to let
us make use of the unit and exponent data provided by HID to set
the [xy]_phy variables to an appropriate value. This function
relies on a trimmed-down version of hidinput_calc_abs_res from
the hid-input.c.

Jason Gerecke 4e90495498 Input: wacom - report correct touch contact size for I5/Bamboo
This changes how the touch packets for Intuos5 and 3rd-gen Bamboo
are interpreted, so that proper values for the MAJOR and MINOR
axes are reported. Instead of using the amplitude field (data[6]),
we use the size field (data[5]) and do some calculation to
transform it from a scaled-down area into axis lengths.

Note that even though we assume a circular contact, both MAJOR and
MINOR are reported since the resolution of the X and Y axes differ.

an out-of-prox packet being sent even if the pad is already out of
prox. This can cause some confusion in the X driver. To restore the
expected semantics, we make being touched a sufficient condition to
signal proximity.

Greg Kroah-Hartman 202712c232 USB: kbtab.c: remove err() usage
err() was a very old USB-specific macro that I thought had
gone away.  This patch removes it from being used in the
driver and uses dev_err() instead.
