Daniel Drake 3b692c55e5 HID: asus: only support backlight when it's not driven by WMI
The Asus GL502VSK has the same 0B05:1837 keyboard as we've seen in
several Republic of Gamers laptops.

However, in this model, the keybard backlight control exposed by hid-asus
has no effect on the keyboard backlight. Instead, the keyboard
backlight is correctly driven by asus-wmi.

With two keyboard backlight devices available (and only the acer-wmi
one working), GNOME is picking the wrong one to drive in the UI.

Avoid this problem by not creating the backlight interface when we
detect a WMI-driven keyboard backlight.

We have also tested Asus GL702VMK which does have the hid-asus
backlight present, and it still works fine with this patch (WMI method
call returns UNSUPPORTED_METHOD).

A direct "depends on ASUS_WMI" is intentionally avoided so that HID_ASUS
users who have ASUS_WMI=n will not quietly lose their HID_ASUS driver on
a kernel upgrade.

Linus Torvalds 044ee89028 HID: input: simplify/fix high-res scroll event handling
Commit 1ff2e1a44e ("HID: input: Create a utility class for counting
scroll events") created the helper function

    hid_scroll_counter_handle_scroll()

to handle high-res scroll events and also expose them as regular wheel
events.

But the resulting algorithm was unstable, and causes scrolling to be
very unreliable.  When you hit the half-way mark of the highres
multiplier, small highres movements will incorrectly translate into big
traditional wheel movements, causing odd jitters.

Simplify the code and make the output stable.

NOTE! I'm pretty sure this will need further tweaking.  But this at
least turns a unusable mouse wheel on my Logitech MX Anywhere 2S into
a usable one.

Linus Torvalds 69d5b97c59 HID: we do not randomly make new drivers 'default y'
.. even when that "default y" is hidden syntactically as a

	default !EXPERT

it's wrong.

The only reason something should be 'default y' is if it used to be
built-in, and it was made configurable, and the 'default y' is just
retaining the status quo.

Altheratively, the hardware for the driver has become _so_ common that
it really makes sense for everybody to build it.  Finally, one possible
reason for 'default y' is because the option is not enabling any new
code at all, but is just enabling other options (the networking people
do this for vendor options, for example, so that you can disable whole
vendors at a time).

Clearly, none of these cases hold for the BigBen Interactive Kids'
gamepad, and HID_BIGBEN_FF should thus most definitely not default
to on for everybody.

Linus Torvalds b59dfdaef1 i2c-hid: properly terminate i2c_hid_dmi_desc_override_table[] array
Commit 9ee3e06610 ("HID: i2c-hid: override HID descriptors for certain
devices") added a new dmi_system_id quirk table to override certain HID
report descriptors for some systems that lack them.

But the table wasn't properly terminated, causing the dmi matching to
walk off into la-la-land, and starting to treat random data as dmi
descriptor pointers, causing boot-time oopses if you were at all
unlucky.

Terminate the array.

We really should have some way to just statically check that arrays that
should be terminated by an empty entry actually are so.  But the HID
people really should have caught this themselves, rather than have me
deal with an oops during the merge window.  Tssk, tssk.

Jason Gerecke 11db8173db HID: wacom: Work around HID descriptor bug in DTK-2451 and DTH-2452
The DTK-2451 and DTH-2452 have a buggy HID descriptor which incorrectly
contains a Cintiq-like report, complete with pen tilt, rotation, twist, serial
number, etc. The hardware doesn't actually support this data but our driver
duitifully sets up the device as though it does. To ensure userspace has a
correct view of devices without updated firmware, we clean up this incorrect
data in wacom_setup_device_quirks.

We're also careful to clear the WACOM_QUIRK_TOOLSERIAL flag since its presence
causes the driver to wait for serial number information (via
wacom_wac_pen_serial_enforce) that never comes, resulting in
the pen being non-responsive.

Hans de Goede afbb1169ed HID: i2c-hid: Remove RESEND_REPORT_DESCR quirk and its handling
Commit 52cf93e63e ("HID: i2c-hid: Don't reset device upon system resume")
removes the need for the RESEND_REPORT_DESCR quirk for Raydium devices, but
kept it for the SIS device id 10FB touchscreens, as the author of that
commit could not determine if the quirk is still necessary there.

I've tested suspend/resume on a Toshiba Click Mini L9W-B which is the
device for which this quirk was added in the first place and with the
"Don't reset device upon system resume" fix the quirk is no longer
necessary, so this commit removes it.

Note even better I also had some other devices with SIS touchscreens which
suspend/resume issues, where the RESEND_REPORT_DESCR quirk did not help.

I've also tested these devices with the "Don't reset device upon system
resume" fix and I'm happy to report that that fix also fixes touchscreen
resume on the following devices:

Asus T100HA
Asus T200TA
Peaq C1010

Anisse Astier 807588ac92 HID: i2c-hid: disable runtime PM operations on hantick touchpad
This hantick HTIX5288 touchpad can quickly fall in a wrong state if
there are too many open/close operations. This will either make it stop
reporting any input, or will shift all the input reads by a few bytes,
making it impossible to decode.

Here, we never release the probed touchpad runtime pm while the driver
is loaded, which should disable all runtime pm suspend/resumes.

This fast repetition of sleep/wakeup is also more likely to happen when
using runtime PM, which is why the quirk is done there, and not for all
power downs, which would include suspend or module removal.

Kai-Heng Feng 52cf93e63e HID: i2c-hid: Don't reset device upon system resume
Raydium touchscreen triggers interrupt storm after system-wide suspend:

	[ 179.085033] i2c_hid i2c-CUST0000:00: i2c_hid_get_input: incomplete report (58/65535)

According to Raydium, Windows driver does not reset the device after system
resume.

The HID over I2C spec does specify a reset should be used at intialization, but
it doesn't specify if reset is required for system suspend.

Tested this patch on other i2c-hid touchpanels I have and those touchpanels do
work after S3 without doing reset. If any regression happens to other
touchpanel vendors, we can use quirk for Raydium devices.

There's still one device uses I2C_HID_QUIRK_RESEND_REPORT_DESCR so keep it
there.
