Subject[v2.6.34-stable 053/165] ALSA: hda/realtek - Avoid bogus HP-pin assignment
Date
From: Takashi Iwai <tiwai@suse.de>

-------------------
This is a commit scheduled for the next v2.6.34 longterm release.
http://git.kernel.org/?p=linux/kernel/git/paulg/longterm-queue-2.6.34.git
If you see a problem with using this for longterm, please comment.
-------------------
commit 5fe6e0151dbd969f5fbcd94d05c968b76d76952b upstream.

When the headphone pin is assigned as primary output to line_out_pins[],
the automatic HP-pin assignment by ASSID must be suppressed. Otherwise
a wrong pin might be assigned to the headphone and breaks the auto-mute.
