Subject: [PATCH 4.1 039/127] ALSA: hda - fix the headset mic detection problem for a Dell laptop

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

------------------

From: Hui Wang <hui.wang@...onical.com>

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.
