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.

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.

.. 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.

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.

My take is that Eaton upgraded their firmwares, so we don't need it

Raydium touchpanel (2386:4B33) sometimes does not work in desktop session
although it works in display manager.
During user logging, the display manager exits, close the HID device,
then the device gets runtime suspended and powered off. The desktop
session begins shortly after, opens the HID device, then the device gets
runtime resumed and powered on.
If the trasition from display manager to desktop sesesion is fast, the
touchpanel cannot switch from powered off to powered on in short
timeframe. So add a small delay to workaround the issue.

uref->usage_index can be indirectly controlled by userspace, hence leading
to a potential exploitation of the Spectre variant 1 vulnerability.
This field is used as an array index by the hiddev_ioctl_usage() function,
when 'cmd' is either HIDIOCGCOLLECTIONINDEX, HIDIOCGUSAGES or
HIDIOCSUSAGES.
For cmd == HIDIOCGCOLLECTIONINDEX case, uref->usage_index is compared to
field->maxusage and then used as an index to dereference field->usage
array. The same thing happens to the cmd == HIDIOC{G,S}USAGES cases, where
uref->usage_index is checked against an array maximum value and then it is
used as an index in an array.
This is a summary of the HIDIOCGCOLLECTIONINDEX case, which matches the
traditional Spectre V1 first load:
copy_from_user(uref, user_arg, sizeof(*uref))
if (uref->usage_index >= field->maxusage)
goto inval;
i = field->usage[uref->usage_index].collection_index;
return i;
This patch fixes this by sanitizing field uref->usage_index before using it
to index field->usage (HIDIOCGCOLLECTIONINDEX) or field->value in
HIDIOC{G,S}USAGES arrays, thus, avoiding speculation in the first load.

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

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.

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.

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.

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

The maximum globale report size has changed from 32->...->96->128 in the past
years. With the development usage of HID, the report_size max value 128 cannot
satisfy all requirements.
There are applications need to expose intrinsic metadata to camera stabilizing
applications such as 3DFE application. 3DFE intrinsic is designed to express
environmental information about sensor that may dynamically change while the
sensor is running (such data include noise spectral density, bias standard
deviation)
A sensor data field is SENSOR_VALUE_PAIR that consists of a PROPERTYKEY and
PROPVARIANT pair. It need to report a unique PROPERTYKEY for each data field.
Take “Noise Spectral Density” as an example, it report count will be
defined as below:
"Size of Property key GUID(16 Byte) + property key index(4 Byte) +
size of Noise Spectral Density value(4 Byte)"
In this case, the data report max is totally 192(24Byte), which is larger than
128, while max size 128 blocked it as illegal length. So increase the report
size to satisfy it and more demands in the future.

On Mehlow Xeon-E workstation, ISH PCI device is enabled but without ISH
firmware. Here the ISH device PCI device id was reused for some non Linux
storage drivers. So this was not done for enabling ISH. But this has a
undesirable side effect for Linux.
Here the ISH driver will be loaded via PCI enumeration and will try to do
reset sequence. But reset sequence will wait till timeout as there is no
real ISH firmware is present to take action. This delay will add to boot
time of Linux (This platform will still continue to boot after this
timeout).
To avoid this boot delay we need to prevent loading of ISH drivers on
this platform. So we need to have hack to avoid treating this device as
ISH on this platform. To identify this workstation, we need some runtime
method. Luckily there are special PCI id on this workstation to
distinguish from the client version of this platform. On client version,
the ISH is supported using same PCI device id. So this change look for
the presence of PCI device IDs A309 and A30A and exit.

Usually, there is no palm rejection for touchscreens. You don't rest
your palm on the touchscreen while interacting with it.
However, some wacom devices do so because you can rest your palm while
interacting with the stylus.
Unfortunately, the spec for touchscreens[1] is less precise than the one
for touchpads[2]. This leads to a situation where it's 'legitimate'
for a touchscreen to provide both tipswitch off and confidence off in the
same report.
Work around that by keeping the slot active for one frame where we report
MT_TOOL_PALM, and then synthesizing the release event in a separate frame.

According to Microsoft specification [1] for Precision Touchpads (and
Touchscreens) the devices use "confidence" reports to signal accidental
touches, or contacts that are "too large to be a finger". Instead of
simply marking contact inactive in this case (which causes issues if
contact was originally proper and we lost confidence in it later, as
this results in accidental clicks, drags, etc), let's report such
contacts as MT_TOOL_PALM and let userspace decide what to do.

The tool works nicely with hid-generic, but it ends up creating 9
different input nodes with most of them only having ABS_MISC set.
Filter the axis out, which reduces the amount of devices to 2. One is
the proper System Multi-axis collection, the other exported device
seems to provide SLEEP and POWER Key, not sure how one can trigger
those events though.
Filtering the ABS_X and ABS_Y axes also prevents udev to detect this as
a touchscreen.

The Dell Canvas 27 has a tool that can be put on the surface and acts
as a dial. The firmware processes the detection of the tool and forward
regular HID reports with X, Y, Azimuth, rotation, width/height.
The firmware also exports Contact ID, Countact Count which may hint that
several totems can be used at the same time (the FW only supports one).
We can tell that MT_TOOL_DIAL will be reported by setting the min/max
of ABS_MT_TOOL_TYPE to MT_TOOL_DIAL.
This tool is aimed at being used by the system and not the applications,
so the user space processing should not go through the regular touch
inputs.
We set INPUT_PROP_DIRECT which applies ID_INPUT_TOUCHSCREEN to this new
type of devices, but we will counter this for the time being with the
special udev hwdb entry mentioned above.

The current way of handling multitouch data is not very straightforward:
- in mt_event() we do nothing
- in mt_report() we:
- do some gym to fetch the scantime and the contact count
- then iterate over the input fields where we copy the data to a
temporary place
- when we see the last field in a slot, we then use this data to emit
the input data
A more streamlined way is to first get all of the address in the report
of all fields, and then just pick the fields we are interested in in
mt_report()
