      HID: i2c-hid: Fix "incomplete report" noise · ef6eaf27
      Jason Andryuk authored 
      Commit ac75a041 ("HID: i2c-hid: fix size check and type usage") started
writing messages when the ret_size is <= 2 from i2c_master_recv.  However, my
device i2c-DLL07D1 returns 2 for a short period of time (~0.5s) after I stop
moving the pointing stick or touchpad.  It varies, but you get ~50 messages
each time which spams the log hard.

[  95.925055] i2c_hid i2c-DLL07D1:01: i2c_hid_get_input: incomplete report (83/2)

This has also been observed with a i2c-ALP0017.

[ 1781.266353] i2c_hid i2c-ALP0017:00: i2c_hid_get_input: incomplete report (30/2)

Only print the message when ret_size is totally invalid and less than 2 to cut
down on the log spam.

      HID: wacom: Correct logical maximum Y for 2nd-gen Intuos Pro large · d471b6b2
      Jason Gerecke authored 
      The HID descriptor for the 2nd-gen Intuos Pro large (PTH-860) contains
a typo which defines an incorrect logical maximum Y value. This causes
a small portion of the bottom of the tablet to become unusable (both
because the area is below the "bottom" of the tablet and because
'wacom_wac_event' ignores out-of-range values). It also results in a
skewed aspect ratio.

To fix this, we add a quirk to 'wacom_usage_mapping' which overwrites
the data with the correct value.

      HID: intel_ish-hid: ipc: register more pm callbacks to support hibernation · ebeaa367
      Even Xu authored 
      Current ISH driver only registers suspend/resume PM callbacks which don't
support hibernation (suspend to disk). Basically after hiberation, the ISH
can't resume properly and user may not see sensor events (for example: screen
		rotation may not work).

User will not see a crash or panic or anything except the following message
in log:

	hid-sensor-hub 001F:8086:22D8.0001: timeout waiting for response from ISHTP device

So this patch adds support for S4/hiberbation to ISH by using the
SIMPLE_DEV_PM_OPS() MACRO instead of struct dev_pm_ops directly. The suspend
and resume functions will now be used for both suspend to RAM and hibernation.

If power management is disabled, SIMPLE_DEV_PM_OPS will do nothing, the suspend
and resume related functions won't be used, so mark them as __maybe_unused to
clarify that this is the intended behavior, and remove #ifdefs for power
management.

      HID: steam: use hid_device.driver_data instead of hid_set_drvdata() · 4bff980f
      Rodrigo Rivas Costa authored 
      When creating the low-level hidraw device, the reference to steam_device
was stored using hid_set_drvdata(). But this value is not guaranteed to
be kept when set before calling probe. If this pointer is reset, it
crashes when opening the emulated hidraw device.

It looks like hid_set_drvdata() is for users "avobe" this hid_device,
while hid_device.driver_data it for users "below" this one.

In this case, we are creating a virtual hidraw device, so we must use
hid_device.driver_data.
