Subject: [059/129] ALSA: hda - Fix wrong HP pin detection in snd_hda_parse_pin_def_config()

2.6.35-stable review patch.  If anyone has any objections, please let us know.

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

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

commit 122661b67899980f1372812d907e73ebcfb3d037 upstream.

snd_hda_parse_pin_def_config() has some workaround for re-assigning
some pins declared as headphones to line-outs.  This didn't work properly
for some cases because it used memmove() stupidly wrongly.
