[PATCH 0/4] Add MSI Claw HID Configuration Driver

[Derek J. Clark]

This series adds and HID Configuration driver for the MSI Claw line of
Handheld Gaming PC's. The MSI Claw HID interface provides multiple
features, such as the ability to switch between xinput, dinput, and a
desktop mode, RGB control, rumble intensity, and mapping of the rear "M"
keys. There are additional gamepad modes that are not included in this
driver as they appear to be used in assembly line testing or are
incomplete in the firmware. During my testing I found them to be unstable.

The initial version of this driver was written by Denis Benato, which
contained the initial reverse-engineering and implementation for the
gamepad mode switching. This work was later expanded by Zhouwang Huang
to include more gamepad modes and additional features. Finally, I
refactored the entire driver, fixed multiple bugs, and refined the overall
format to conform to kernel driver best practices and style guide.

Claude was used initially by Zhouwang Huang to quickly parse HID captures
during the reverse-engineering of some of the features. Since Claude had
already been used, as a test of its capabilities I had it implement the
rumble intensity attribute after I had already rewritten most of the
driver, which I then manually edited to fix some mistakes. I also used
Claude to review the driver and these patches for any mistakes and bugs.
