Subject: [PATCH 3.19.y-ckt 020/130] ALSA: hda - Add headset mic support for Acer Aspire V5-573G

3.19.8-ckt6 -stable review patch.  If anyone has any objections, please let me know.

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

From: Mateusz Sylwestrzak <matisec7@...il.com>

commit 0420694dddeb9e269a1ab2129a0119a5cea294a4 upstream.

Acer Aspire V5 with the ALC282 codec is given the wrong value for the
0x19 PIN by the laptop's BIOS. Overriding it with the correct value
adds support for the headset microphone which would not otherwise be
visible in the system.

The fix is based on commit 7819717b1134 with a similar quirk for Acer
Aspire with the ALC269 codec.
