Subject[PATCH 3.12 160/212] ALSA: hda - Fix hp-mic mode without VREF bits
Date
3.12-stable review patch.  If anyone has any objections, please let me know.

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

From: Takashi Iwai <tiwai@suse.de>

commit 16c0cefe8951b2c4b824fd06011ac1b359b1ab3b upstream.

When the hp mic pin has no VREF bits, the driver forgot to set PIN_IN
bit. Spotted during debugging old MacBook Airs.
