When an I2C SMBus read operation fails, the MCP2221 internal state machine
may not reset correctly, causing subsequent transactions to fail.
By adding a short delay and explicitly cancelling the last command,
we ensure the device is ready for the next operation.
Fix an issue where i2cdetect was not able to detect all devices correctly
on the bus.

Uniwill devices have a built in gesture in the touchpad to de- and
reactivate it by double taping the upper left corner. This gesture stops
working when latency is set to high, so this patch keeps the latency on
normal.

EPOMAKER TH87 has the very same ID as Apple Aluminum keyboard
(05ac:024f) although it doesn't work as expected in compatible way.
Put three entries to the non-apple keyboards list to exclude this
device: one for BT ("TH87"), one for USB ("HFD Epomaker TH87") and one
for dongle ("2.4G Wireless Receiver").

Battery reporting does not work for the Apple Magic Trackpad 2 if it is
connected via USB. The current hid descriptor fixup code checks for a
hid descriptor length of exactly 83 bytes. If the hid descriptor is
larger, which is the case for newer apple mice, the fixup is not
applied.
This fix checks for hid descriptor sizes greater/equal 83 bytes which
applies the fixup for newer devices as well.

This converts some of the visually simpler cases that have been split
over multiple lines. I only did the ones that are easy to verify the
resulting diff by having just that final GFP_KERNEL argument on the next
line.
Somebody should probably do a proper coccinelle script for this, but for
me the trivial script actually resulted in an assertion failure in the
middle of the script. I probably had made it a bit _too_ trivial.
So after fighting that far a while I decided to just do some of the
syntactically simpler cases with variations of the previous 'sed'
scripts.
The more syntactically complex multi-line cases would mostly really want
whitespace cleanup anyway.

This was done entirely with mindless brute force, using
git grep -l '\<k[vmz]*alloc_objs*(.*, GFP_KERNEL)' |
xargs sed -i 's/\(alloc_objs*(.*\), GFP_KERNEL)/\1)/'
to convert the new alloc_obj() users that had a simple GFP_KERNEL
argument to just drop that argument.
Note that due to the extreme simplicity of the scripting, any slightly
more complex cases spread over multiple lines would not be triggered:
they definitely exist, but this covers the vast bulk of the cases, and
the resulting diff is also then easier to check automatically.
For the same reason the 'flex' versions will be done as a separate
conversion.

This is the result of running the Coccinelle script from
scripts/coccinelle/api/kmalloc_objs.cocci. The script is designed to
avoid scalar types (which need careful case-by-case checking), and
instead replace kmalloc-family calls that allocate struct or union
object instances:
Single allocations: kmalloc(sizeof(TYPE), ...)
are replaced with: kmalloc_obj(TYPE, ...)
Array allocations: kmalloc_array(COUNT, sizeof(TYPE), ...)
are replaced with: kmalloc_objs(TYPE, COUNT, ...)
Flex array allocations: kmalloc(struct_size(PTR, FAM, COUNT), ...)
are replaced with: kmalloc_flex(*PTR, FAM, COUNT, ...)
(where TYPE may also be *VAR)
The resulting allocations no longer return "void *", instead returning
"TYPE *".

In commit 2ff5baa9b527 ("HID: appleir: Fix potential NULL dereference at
raw event handle"), we handle the fact that raw event callbacks
can happen even for a HID device that has not been "claimed" causing a
crash if a broken device were attempted to be connected to the system.
Fix up the remaining in-tree HID drivers that forgot to add this same
check to resolve the same issue.

The asus_report_fixup() function was returning a newly allocated
kmemdup()-allocated buffer, but never freeing it. Switch to
devm_kzalloc() to ensure the memory is managed and freed automatically
when the device is removed.
The caller of report_fixup() does not take ownership of the returned
pointer, but it is permitted to return a pointer whose lifetime is at
least that of the input buffer.
Also fix a harmless out-of-bounds read by copying only the original
descriptor size.

During a warm reset flow, the cl->device pointer may be NULL if the
reset occurs while clients are still being enumerated. Accessing
cl->device->reference_count without a NULL check leads to a kernel panic.
This issue was identified during multi-unit warm reboot stress clycles.
Add a defensive NULL check for cl->device to ensure stability under
such intensive testing conditions.

Some ROG laptops expose multiple interfaces for controlling the
keyboard/RGB brightness. This creates a name conflict under
asus::kbd_brightness, where the second device ends up being
named asus::kbd_brightness_1 and they are both broken.
Therefore, register a listener to the asus-wmi brightness device
instead of creating a new one.

Some ROG devices have a new dynamic backlight interface for control by
Windows. This interface does not create an ->input device, causing the
kernel to print an error message and to eject it. In addition, ROG
devices have proper HID names in their descriptors so renaming them is
not necessary.
Therefore, if a device is identified as ROG, early return from probe to
skip renaming and ->input checks.

ROG NKEY devices have multiple HID endpoints, around 3-4. One of those
endpoints has a usage page of 0xff31, and is the one that emits keyboard
shortcuts and controls RGB/backlight. Currently, this driver places
the usage page check under asus_input_mapping and then inits backlight
in asus_input_configured which is unnecessarily complicated and prevents
probe from performing customizations on the vendor endpoint.
Simplify the logic by introducing an is_vendor variable into probe that
checks for usage page 0xff31. Then, use this variable to move backlight
initialization into probe instead of asus_input_configured, and remove
the backlight check from asus_input_mapping.

Handshaking with an Asus device involves sending it a feature report
with the string "ASUS Tech.Inc." and then reading it back to verify the
handshake was successful, under the feature ID the interaction will
take place.
Currently, the driver only does the first part. Add the readback to
verify the handshake was successful. As this could cause breakages,
allow the verification to fail with a dmesg error until we verify
all devices work with it (they seem to).
Since the response is more than 16 bytes, increase the buffer size
to 64 as well to avoid overflow errors. In addition, add the report
ID to prints, to help identify failed handshakes.
