Subject: [PATCH 3.2 020/102] ALSA: hda - Fix COEF setups for ALC1150 codec

3.2.64-rc1 review patch.  If anyone has any objections, please let me know.

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

From: Takashi Iwai <tiwai@...e.de>

commit acf08081adb5e8fe0519eb97bb49797ef52614d6 upstream.

ALC1150 codec seems to need the COEF- and PLL-setups just like its
compatible ALC882 codec.  Some machines (e.g. SunMicro X10SAT) show
the problem like too low output volumes unless the COEF setup is
applied.
