Subject: [PATCH] HID: Add Mapping for System Microphone Mute
Git-commit: 2d60f9f4f26785a00273cb81fe60eff129ebd449
Patch-mainline: v6.3-rc1
References: git-fixes
HUTRR110 added a new usage code for a key that is supposed to
mute/unmute microphone system-wide.
Map the new usage code(0x01 0xa9) to keycode KEY_MICMUTE.
Additionally hid-debug is adjusted to recognize this keycode as well.
