Subject: [PATCH] ALSA: hda - Fix silent headphone output from Toshiba P200

commit cb766404e6b8c566569eb9ada02ea45d28729864 upstream.

By some reason, Toshiba laptop doesn't like the EAPD turned up for the
headphone pin.  Add a fix up code to force to turn down EAPD for NID
0x15.

[ herton: backported to 3.5:
  create enum/structs from scratch, instead of bringing
  commit 6e72aa5f. alc_apply_fixup with ALC_FIXUP_ACT_PRE_PROBE should
  be a noop on this, but keep it as it's a skeleton for possible
  quirks in the future being applied through stable ]
