[SRU][A/B/OEM-A][PATCH] Enable mic-mute hotkey and led for Lenovo M810z, M820z and M920z

[Hui Wang]

Hello Po-Hsu,

It is in the git://git.kernel.org/pub/scm/linux/kernel/git/tiwai/sound.git

And it will be merged to upstream kernel soon.

And I added this info in the patch as this:

(cherry picked from commit 986376b68dcc95bb7df60ad30c2353c1f7578fa5
git://git.kernel.org/pub/scm/linux/kernel/git/tiwai/sound.git)



Thank you very much.
Hui.
