+Subject: ALSA: hda - Fix GPIO for Acer Aspire 3830TG
+
+From: Takashi Iwai <tiwai@suse.de>
+
+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.
