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.

asus::kbd_brightness, where the second device ends up being
named asus::kbd_brightness_1 and they are both broken.

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.

Currently, ID1/ID2 initializations are performed for all NKEY devices.
However, ID1 initializations are only required for RGB control and are
only supported for RGB capable devices. ID2 initializations are only
required for initializing the Anime display endpoint which is only
supported on devices with an Anime display. Both of these
initializations are for functionality that is not present on this driver
and are performed for devices which might not support them.
At the same time, there are older NKEY devices that have only been
tested with these initializations in the kernel and it is not possible
to recheck them. There is a possibility that especially with the ID1
initialization, certain laptop models might have their shortcuts stop
working (currently unproven).
To avoid sending unnecessary commands, change to only initialize ID1/ID2
for those NKEY devices suspected to be problematic without them by
introducing a quirk for them and replacing the NKEY quirk in the block
that performs the inits with that. Therefore, new devices that do not
need (and some do not support) these initializations will not have
them performed.
In addition, as these initializations might not be supported by the
affected devices, change the function to not bail if they fail.

Currently, RGB initialization forks depending on whether a device is
NKEY. However, in reality both initialization forks are the same, other
than the NKEY initialization initializing the LED_REPORT_ID1,
LED_REPORT_ID2 endpoints, and the non-NKEY initialization having a
functionality check which is skipped for the NKEY path.
Therefore, merge the if blocks, gate the ID1/ID2 initializations
behind the NKEY quirk instead, and introduce the functionality check
for NKEY devices (it is supported by them).
There should be no functional change with this patch.

driver to actually change the fan mode.
Add ASUS_FAN_CTRL_KEY_CODE define and implement the handler in
asus_raw_event() to send WMI events when this key is pressed.
When asus-wmi successfully handles the event, it is blocked from reaching
userspace. If asus-wmi is unavailable or fails, the event is passed to
userspace via evdev, allowing userspace implementations of fan control.

The fw_attributes_class provides a much cleaner interface to all of the
attributes introduced to asus-wmi. This patch moves all of these extra
attributes over to fw_attributes_class, and shifts the bulk of these
definitions to a new kernel module to reduce the clutter of asus-wmi
with the intention of deprecating the asus-wmi attributes in future.
The work applies only to WMI methods which don't have a clearly defined
place within the sysfs and as a result ended up lumped together in
/sys/devices/platform/asus-nb-wmi/ with no standard API.
Where possible the fw attrs now implement defaults, min, max, scalar,
choices, etc. As en example dgpu_disable becomes:
/sys/class/firmware-attributes/asus-armoury/attributes/dgpu_disable/
├── current_value
├── display_name
├── possible_values

After hid_hw_start() is called hidinput_connect() will eventually be
called to set up the device with the input layer since the
HID_CONNECT_DEFAULT connect mask is used. During hidinput_connect()
all input and output reports are processed and corresponding hid_inputs
are allocated and configured via hidinput_configure_usages(). This
process involves slot tagging report fields and configuring usages
by setting relevant bits in the capability bitmaps. However it is possible
that the capability bitmaps are not set at all leading to the subsequent
hidinput_has_been_populated() check to fail leading to the freeing of the
hid_input and the underlying input device.
This becomes problematic because a malicious HID device like a
ASUS ROG N-Key keyboard can trigger the above scenario via a
specially crafted descriptor which then leads to a user-after-free
when the name of the freed input device is written to later on after
hid_hw_start(). Below, report 93 intentionally utilises the
HID_UP_UNDEFINED Usage Page which is skipped during usage
configuration, leading to the frees.

Adjust how the CSEE direct call hack is used.
The results of months of testing combined with help from ASUS to
determine the actual cause of suspend issues has resulted in this
refactoring which immensely improves the reliability for devices which
do not have the following minimum MCU FW version:
- ROG Ally X: 313
- ROG Ally 1: 319
For MCU FW versions that match the minimum or above the CSEE hack is
disabled and mcu_powersave set to on by default as there are no
negatives beyond a slightly slower device reinitialization due to the
MCU being powered off.
As this is set only at module load time, it is still possible for
mcu_powersave sysfs attributes to change it at runtime if so desired.

This patch addresses only the ProArt series so far and it is unknown if

Merge tag 'hwmon-for-v6.11-rc7' into review-hans
Merge "hwmon fixes for v6.11-rc7" into review-hans to bring in
commit a54da9df75 ("hwmon: (hp-wmi-sensors) Check if WMI event
data exists").
This is a dependency for a set of WMI event data refactoring changes.
By allowing the drivers to return a "const *" they can constify their
static report arrays.
This makes it clear to driver authors that the HID core will not modify
those reports and they can be reused for multiple devices.
Furthermore security is slightly improved as those reports are protected
against accidental or malicious modifications.

On almost all ASUS ROG series laptops the MCU used for the USB keyboard
also has a HID packet used for setting the brightness. This is usually
the same as the WMI method. But in some laptops the WMI method either
is missing or doesn't work, so we should default to the HID control.

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.

These two keys are found on some models with dual display.
- 0x6a is intended for controlling the secondary screen brightness.
- 0x4b is intended for toggling the arrow keys between arrows and
page up / page down.
This key is found on a slightly modified keyboard layout.
- 0xc7 is intended to cycle through keybvoard brightnesses (upwards) but
there is not suitable existing code for this behaviour. Using
`KEY_KBDILLUMTOGGLE` is different behaviour to Windows but at least

A number of HID drivers already call hid_is_using_ll_driver() but only
for the detection of if this is a USB device or not. Make this more
obvious by creating hid_is_usb() and calling the function that way.
Also converts the existing hid_is_using_ll_driver() functions to use the
new call.
