Re: [PATCH v2] HID: input: map System Microphone Mute LED

HUTRR110 defines LED page usage 0x57 as System Microphone Mute.

The usage is currently ignored, so the indicator stays dark and
userspace falls back to per-vendor code in hid-lenovo,
hid-playstation, hid-plantronics.

Map it to a new LED_MICMUTE. It appears as
/sys/class/leds/inputN::micmute and uses the "audio-micmute"
trigger from snd-ctl-led, so the LED follows the system-wide
mic mute state the same way LED_MUTE (page 0x09) already does
for speaker mute.

LED_MICMUTE takes the next free code (0x0b).
