Adds intensity adjustment for the left and right rumble motors.
Claude was used during the reverse-engineering data gathering for this
feature done by Zhouwang Huang. As the code had already been affected,
I used Claude to create the initial framing for the feature, then did
manual cleanup of the _show and _store functions afterwards to fix bugs
and keep the coding style consistent. Claude was also used as an initial
reviewer of this patch.

Adds RGB control interface for MSI Claw devices. The MSI Claw uses a
fairly unique RGB interface. It has 9 total zones (4 per joystick ring
and 1 for the ABXY buttons), and supports up to 8 sequential frames of
RGB zone data. Each frame is written to a specific area of MCU memory by
the profile command, the value of which changes based on the firmware of
the device. Unlike other devices (such as the Legion Go or the OneXPlayer
devices), there are no hard coded effects built into the MCU. Instead,
the basic effects are provided as a series of frame data. I have
mirrored the effects available in Windows in this driver, while keeping
the effect names consistent with the Lenovo drivers for the effects that
are similar.
Initial reverse-engineering and implementation of this feature was done
by Zhouwang Huang. I refactored the overall format to conform to kernel
driver best practices and style guides. Claude was used as an initial
reviewer of this patch.

Adds attributes that allow for remapping the M-keys with up to 5 values
when in macro mode. There are 2 mappable buttons on the rear of the
device, M1 on the right and M2 on the left. When mapped, the events will
fire from one of three event devices: gamepad buttons will fire from the
device handled by xpad, while keyboard and mouse events will fire from
respectively typed evdevs provided by the input core. Names of each
mapping have been kept as close to the event that will fire from the evdev
as possible, with context added to the ABS_ events on the direction of the
movement.

Adds configuration HID driver for the MSI Claw series of handheld PC's.
In this initial patch add the initial driver outline and attributes for
changing the gamepad mode, M-key behavior, and add a WO reset function.
Sending the SWITCH_MODE and RESET commands causes a USB disconnect in
the device. The completion will therefore never get hit and would trigger
an -EIO. To avoid showing the user an error for every write to these
attrs a bypass for the completion handling is introduced when timeout ==
0.
The initial version of this patch 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. Finally, I refactored the drivers data
in/out flow and overall format to conform to kernel driver best
practices and style guides. Claude was used as an initial reviewer of
this patch.
