Subject: [ 42/69] ALSA: hda - Suppress auto-mute feature on some machines with ALC861

3.2-stable review patch.  If anyone has any objections, please let me know.

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

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

commit e652f4c861fb7f1f59ff0828db0d85578471932d upstream.

A few machines with ALC861 & co are reported not to work properly with
the auto-mute feature in software.  The auto-mute feature is implemented
in the hardware level, and the jack-detection never works with them.

Also, rename the fixup index as ALC861_FIXUP_* to follow the standard.
