From: Jingyuan Liang <redacted> [ Upstream commit 2d60f9f4f26785a00273cb81fe60eff129ebd449 ] 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.
