[alsa-devel] [PATCH] ALSA: hda - Add headset mic support for Acer Aspire V5-573G

[Takashi Iwai]

From: Mateusz Sylwestrzak <matisec7 at gmail.com>

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.
