Subject: [v2.6.34-stable 053/165] ALSA: hda/realtek - Avoid bogus HP-pin assignment

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