[ Upstream commit 8031b001da700474c11d28629581480b12a0d8d4 ]
Sensors discovery is independent of HID device initialization. If sensor
discovery fails after HID initialization, then the HID device needs to be
deinitialized. Therefore, sensors discovery should be moved before HID
device initialization.

[ Upstream commit 4aa2dcfbad538adf7becd0034a3754e1bd01b2b5 ]
Syzkaller hit a warning [1] in a call to implement() when trying
to write a value into a field of smaller size in an output report.
Since implement() already has a warn message printed out with the
help of hid_warn() and value in question gets trimmed with:
...
value &= m;
...
WARN_ON may be considered superfluous. Remove it to suppress future
syzkaller triggers.

commit 0eafc58f2194dbd01d4be40f99a697681171995b upstream.
The Elan eKTH5015M touch controller found on the Lenovo ThinkPad X13s
shares the VCC33 supply with other peripherals that may remain powered
during suspend (e.g. when enabled as wakeup sources).
The reset line is also wired so that it can be left deasserted when the
supply is off.
This is important as it avoids holding the controller in reset for
extended periods of time when it remains powered, which can lead to
increased power consumption, and also avoids leaking current through the
X13s reset circuitry during suspend (and after driver unbind).
Use the new 'no-reset-on-power-off' devicetree property to determine
when reset needs to be asserted on power down.
Notably this also avoids wasting power on machine variants without a
touchscreen for which the driver would otherwise exit probe with reset
asserted.

commit 9c0f59e47a90c54d0153f8ddc0f80d7a36207d0e upstream.
The flag I2C_HID_READ_PENDING is used to serialize I2C operations.
However, this is not necessary, because I2C core already has its own
locking for that.
More importantly, this flag can cause a lock-up: if the flag is set in
i2c_hid_xfer() and an interrupt happens, the interrupt handler
(i2c_hid_irq) will check this flag and return immediately without doing
anything, then the interrupt handler will be invoked again in an
infinite loop.
Since interrupt handler is an RT task, it takes over the CPU and the
flag-clearing task never gets scheduled, thus we have a lock-up.
Delete this unnecessary flag.

commit c1d6708bf0d3dd976460d435373cf5abf21ce258 upstream.
If a input device is opened before hid_hw_start is called, events may
not be received from the hardware. In the case of USB-backed devices,
for example, the hid_hw_start function is responsible for filling in
the URB which is submitted when the input device is opened. If a device
is opened prematurely, polling will never start because the device will
not have been in the correct state to send the URB.
Because the wacom driver registers its input devices before calling
hid_hw_start, there is a window of time where a device can be opened
and end up in an inoperable state. Some ARM-based Chromebooks in particular
reliably trigger this bug.
This commit splits the wacom_register_inputs function into two pieces.
One which is responsible for setting up the allocated inputs (and runs
prior to hid_hw_start so that devices are ready for any input events
they may end up receiving) and another which only registers the devices
(and runs after hid_hw_start to ensure devices can be immediately opened
without issue). Note that the functions to initialize the LEDs and remotes
are also moved after hid_hw_start to maintain their own dependency chains.

commit ab41a31dd5e2681803642b6d08590b61867840ec upstream.
The xf86-input-wacom driver does not treat '0' as a valid serial
number and will drop any input report which contains an
MSC_SERIAL = 0 event. The kernel driver already takes care to
avoid sending any MSC_SERIAL event if the value of serial[0] == 0
(which is the case for devices that don't actually report a
serial number), but this is not quite sufficient.
Only the lower 32 bits of the serial get reported to userspace,
so if this portion of the serial is zero then there can still
be problems.
This commit allows the driver to report either the lower 32 bits
if they are non-zero or the upper 32 bits otherwise.

commit 7cdd2108903a4e369eb37579830afc12a6877ec2 upstream.
When the kfunc hid_bpf_attach_prog() is called, we called twice fdget():
one for fetching the type of the bpf program, and one for actually
attaching the program to the device.
The problem is that between those two calls, we have no guarantees that
the prog_fd is still the same file descriptor for the given program.
Solve this by calling bpf_prog_get() earlier, and use this to fetch the
program type.

commit 502296030ec6b0329e00f9fb15018e170cc63037 upstream.
There appear to be a few different ways that Wacom devices can deal with
confidence:
1. If the device looses confidence in a touch, it will first clear
the tipswitch flag in one report, and then clear the confidence
flag in a second report. This behavior is used by e.g. DTH-2452.
2. If the device looses confidence in a touch, it will clear both
the tipswitch and confidence flags within the same report. This
behavior is used by some AES devices.
3. If the device looses confidence in a touch, it will clear *only*
the confidence bit. The tipswitch bit will remain set so long as
the touch is tracked. This behavior may be used in future devices.
The driver does not currently handle situation 3 properly. Touches that
loose confidence will remain "in prox" and essentially frozen in place
until the tipswitch bit is finally cleared. Not only does this result
in userspace seeing a stuck touch, but it also prevents pen arbitration
from working properly (the pen won't send events until all touches are
up, but we don't currently process events from non-confident touches).
This commit centralizes the checking of the confidence bit in the
wacom_wac_finger_slot() function and has 'prox' depend on it. In the
case where situation 3 is encountered, the treat the touch as though
it was removed, allowing both userspace and the pen arbitration to
act normally.

commit 8e2f79f41a5d1b1a4a53ec524eb7609ca89f3c65 upstream.
After the commit 666cf30a589a ("HID: sensor-hub: Allow multi-function
sensor devices") hub devices are claimed by hidraw driver in hid_connect().
This causes stoppping of processing HID reports by hid core due to
optimization.
In such case, the hid-sensor-custom driver cannot match a known custom
sensor in hid_sensor_custom_get_known() because it try to check custom
properties which weren't filled from the report because hid core didn't
parsed it.
As result, custom sensors like hinge angle sensor and LISS sensors
don't work.
Mark the sensor hub devices claimed by some driver to avoid hidraw-related
optimizations.

a kernel crash on Steam Deck, with the below panic spew:

Since it's a divide-by-0 error, by tracking the code for potential
denominator issues, we've spotted 2 places in which this could happen;
so let's guard against the possibility and log in the kernel if the
condition happens. This is specially useful since some data that
fills some denominators are read from the joycon HW in some cases,
increasing the potential for flaws.

Honor MagicBook 13 2023 has a touchpad which do not switch to the multitouch

report the input mode at touchpad(3), while itself working under mouse mode. As
a workaround, it is possible to call MT_QUIRE_FORCE_GET_FEATURE to force set
feature in mt_set_input_mode for such device.
The touchpad reports as BLTP7853, which cannot retrive any useful manufacture
information on the internel by this string at present. As the serial number of
the laptop is GLO-G52, while DMI info reports the laptop serial number as
GLO-GXXX, this workaround should applied to all models which has the GLO-GXXX.

Some devices managed by this driver automatically set brightness to 0
before entering a suspended state and reset it back to a default
brightness level after the resume:
this has the effect of having the kernel report wrong brightness
status after a sleep, and on some devices (like the Asus RC71L) that
brightness is the intensity of LEDs directly facing the user.
Fix the above issue by setting back brightness to the level it had
before entering a sleep state.

[ Upstream commit a5e913c25b6b2b6ae02acef6d9400645ac03dfdf ]
The Glorious Model I mouse has a buggy HID report descriptor for its
keyboard endpoint (used for programmable buttons). For report ID 2, there
is a mismatch between Logical Minimum and Usage Minimum in the array that
reports keycodes.
The offending portion of the descriptor: (from hid-decode)
0x95, 0x05, // Report Count (5) 30
0x75, 0x08, // Report Size (8) 32
0x15, 0x00, // Logical Minimum (0) 34
0x25, 0x65, // Logical Maximum (101) 36
0x05, 0x07, // Usage Page (Keyboard) 38
0x19, 0x01, // Usage Minimum (1) 40
0x29, 0x65, // Usage Maximum (101) 42
0x81, 0x00, // Input (Data,Arr,Abs) 44
This bug shifts all programmed keycodes up by 1. Importantly, this causes
"empty" array indexes of 0x00 to be interpreted as 0x01, ErrorRollOver.
The presence of ErrorRollOver causes the system to ignore all keypresses
from the endpoint and breaks the ability to use the programmable buttons.
Setting byte 41 to 0x00 fixes this, and causes keycodes to be interpreted
correctly.
Also, USB_VENDOR_ID_GLORIOUS is changed to USB_VENDOR_ID_SINOWEALTH,
and a new ID for Laview Technology is added. Glorious seems to be
white-labeling controller boards or mice from these vendors. There isn't a
single canonical vendor ID for Glorious products.

[ Upstream commit 73ce9f1f2741a38f5d27393e627702ae2c46e6f2 ]
During the probe we add an I2C adapter and as soon as we add that adapter
it may be used for a transfer (e.g via the code in i2cdetect()).
Those transfers are not able to complete and time out. This is because the
HID raw_event callback (mcp2221_raw_event) will not be invoked until the
HID device's 'driver_input_lock' is marked up at the completion of the
probe in hid_device_probe(). This starves the driver of the responses it
is waiting for.
In order to allow the I2C transfers to complete while we are still in the
probe, start the IO once we have completed init of the HID device.
This issue seems to have been seen before and a patch was submitted but
it seems it was never accepted. See:

commit a9f68ffe1170ca4bc17ab29067d806a354a026e0 upstream.
Users have reported problems with recent Lenovo laptops that contain
an IDEA5002 I2C HID device. Reports include fans turning on and
running even at idle and spurious wakeups from suspend.
Presumably in the Windows ecosystem there is an application that
uses the HID device. Maybe that puts it into a lower power state so
it doesn't cause spurious events.
This device doesn't serve any functional purpose in Linux as nothing
interacts with it so blacklist it from being probed. This will
prevent the GPIO driver from setting up the GPIO and the spurious
interrupts and wake events will not occur.

commit 2f2bd7cbd1d1548137b351040dc4e037d18cdfdc upstream.
The USB Compact Keyboard variant requires a reset_resume function to
restore keyboard configuration after a suspend in some situations. Move
configuration normally done on probe to lenovo_features_set_cptkbd(), then
recycle this for use on reset_resume.
Without, the keyboard and driver would end up in an inconsistent state,
breaking middle-button scrolling amongst other problems, and twiddling
sysfs values wouldn't help as the middle-button mode won't be set until
the driver is reloaded.
Tested on a USB and Bluetooth Thinkpad Compact Keyboard.

[ Upstream commit 46a0a2c96f0f47628190f122c2e3d879e590bcbe ]
Built-in firmware of cptkbd handles scrolling by itself (when middle
button is pressed) but with issues: it does not support horizontal and
hi-res scrolling and upon middle button release it sends middle button
click even if there was a scrolling event. Commit 3cb5ff0220e3 ("HID:
lenovo: Hide middle-button press until release") workarounds last
issue but it's impossible to workaround scrolling-related issues
without firmware modification.
Likely, Dennis Schneider has reverse engineered the firmware and
provided an instruction on how to patch it [1]. However,
aforementioned workaround prevents userspace (libinput) from knowing
exact moment when middle button has been pressed down and performing
"On-Button scrolling". This commit detects correctly-behaving patched
firmware if cursor movement events has been received during middle
button being pressed and stops applying workaround for this device.
