Subject: [PATCH] [120/223] ALSA: HDA: Add an extra DAC for Realtek ALC887-VD

2.6.35-longterm review patch.  If anyone has any objections, please let me know.

------------------
From: David Henningsson <david.henningsson@...onical.com>

commit cc1c452e509aefc28f7ad2deed75bc69d4f915f7 upstream.

The patch enables ALC887-VD to use the DAC at nid 0x26,
which makes it possible to use this DAC for e g Headphone
volume.
