Today Lenovo Thinkpads are coming with a new key for muting the
microphone. They started this with the T400s & it is now on T410(s)/510,
W510/W710, L412/512, X100e, Edge 13/14/15 Thinkpads. Currently 12
models, with more coming in the foreseeable future.
I want to define a keycode for microphone mute to be able take advantage
of this key in userspace.
The only issue is I'm not sure the best code to use, or if these are
defined from somewhere else? Here is what I propose .. though feedback
would be greatly appreciated.
