Lenovo is now including a key for muting the microphone on all Thinkpad models & peripheral keyboards. Currently there is no way to deal with this key being handled in a common fashion under Linux. This patch defines a key code for microphone mute so that this key can be mapped for Thinkpad models & peripheral keyboards. By having a set keycode this key can be remapped to the common keycode and userspace can then listen and take some action once the key is pressed. A common action would be to mute the microphone mixer.
