Subject: ALSA: hda - Fix GPIO for Acer Aspire 3830TG
From: Takashi Iwai <tiwai@xxxxxxx>
commit 4a4370442c996be0fd08234a167c8a127c2488bb upstream.
Acer Aspire 3830TG seems requiring GPIO bit 0 as the primary mute
control. When a machine is booted after Windows 8, the GPIO pin is
turned off and it results in the silent output.
This patch adds the manual fixup of GPIO bit 0 for this model.
