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 *".

Many controllers these days have started including grip buttons. As
there has been no particular assigned BTN_* constants for these, they've
been haphazardly assigned to BTN_TRIGGER_HAPPY*. Unfortunately, the
assignment of these has varied significantly between drivers.
Add and document new constants for these grip buttons.

BTN_WHEEL is duplicated (by value) and compiler is not happy about that:
drivers/hid/hid-debug.c:3302:16: error: initializer overrides prior initialization of this subobject [-Werror,-Winitializer-overrides]

Remove it again, as the commit 7b2daa648e ("HID: debug: Remove duplicates
from 'keys'") already did this once in the past.

The name of BTN_GEAR_DOWN was WheelBtn and BTN_WHEEL was missing. Further,
BTN_GEAR_UP had a space in its name and no Btn, which is against convention.
This makes the names BtnGearDown, BtnGearUp, and BtnWheel, fixing the errors
and matching convention.

When detecting an invalid list->hdev, the process needs to manually set
its state to TASK_RUNNING and exit. In the original code,
set_current_state() (which includes a memory barrier) is used here, but
it is immediately followed by a mutex_unlock() call. Since
mutex_unlock() internally includes a memory barrier, this ensures that
all modifications within the critical section (including the process
state) are visible to other CPUs. Therefore, replacing it with
__set_current_state() (without an implicit barrier) avoids redundant
memory barriers.

Duplicates in 'keys prevents kernel builds with clang, `make W=1` and
CONFIG_WERROR=y, for example:
drivers/hid/hid-debug.c:3443:18: error: initializer overrides prior initialization of this subobject [-Werror,-Winitializer-overrides]
3443 | [KEY_HANGEUL] = "HanGeul", [KEY_HANGUP_PHONE] = "HangUpPhone",

drivers/hid/hid-debug.c:3217:18: note: previous initialization is here
3217 | [KEY_HANGUEL] = "Hangeul", [KEY_HANJA] = "Hanja",
| ^~~~~~~~~
Fix this by removing them.
The logic of removal is that, remove...
1) if there is a constant that uses another defined constant, OR
2) the one that appears later in the list.

Currently hid-debug's hid_resolv_event prints questions marks for
all entries without explicit mapping information. This makes
debugging unnecessarily complicated as multiple different
keys may simply result in the same uninformative output.
Some common event codes are deliberately not defined in
input-event-codes.h. For example the 16th gamepad key.
Instead, print the hexadecimal codes for all events without symbolic
names.

Hid-debug's rdesc output for a game controller contained a few question
marks and numeric IDs instead of the expected descriptive names.
This happens because:
1) the mapping data is missing event codes defined in input-event-codes.h
2) HID usages aren't up to date
3) hid_resolv_usage fails to account for the sensor pages' modifiers
Add missing event codes and update HID to HUT 1.5.
