Subject: ALSA: hda - fix front mic problem for a HP desktop

From: Hui Wang <[email protected]>

commit e549d190f7b5f94e9ab36bd965028112914d010d upstream.

The front mic jack (pink color) can't detect any plug or unplug. After applying this fix, both detecting function and recording function work well.
