From: Kamal Mostafa
Date: Wed Jan 27 2016 - 16:34:37 EST

4.2.8-ckt3 -stable review patch. If anyone has any objections, please let me know.


From: Hui Wang <hui.wang@xxxxxxxxxxxxx>

commit 0a1f90a982e85f4921bed606a6b41a24f4de2ae1 upstream.

The machine uses codec alc255, and the pin configuration value for
pin 0x14 on this machine is 0x90171130 which is not in the pin quirk
table yet.
