Subject: [PATCH 3.13 18/40] ALSA: hda - Fix missing VREF setup for Mac Pro 1,1

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

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

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

commit c20f31ec421ea4fabea5e95a6afd46c5f41e5599 upstream.

Mac Pro 1,1 with ALC889A codec needs the VREF setup on NID 0x18 to
VREF50, in order to make the speaker working.  The same fixup was
already needed for MacBook Air 1,1, so we can reuse it.
