Subject: ALSA: hda - Fix digital mic on Acer Aspire 3830TG
From: Takashi Iwai <tiwai@xxxxxxx>
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.
