Subject: [PATCH 3.11 110/131] ALSA: hda - Add a fixup for HP Folio 13 mute LED

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

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

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

commit 37c367ecdb9a01c9acc980e6e17913570a1788a7 upstream.

HP Folio 13 may have a broken BIOS that doesn't set up the mute LED
GPIO properly, and the driver guesses it wrongly, too.  Add a new
fixup entry for setting the GPIO pin statically for this laptop.
