Subject: [PATCH 3.16 059/357] ALSA: hda - Fix digital mic on Acer Aspire 3830TG

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

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

From: Takashi Iwai <tiwai@...e.de>

commit ff50479ad61069f3ee14863225aebe36d598e93e upstream.

Acer Aspire 3830TG with CX20588 codec has a digital built-in mic that
has the same problem like many others, the inverted signal in stereo.
Apply the same fixup to this machine, too.
