Subject: [PATCH 3.16 290/370] ALSA: hda - adding a new NV HDMI/DP codec ID
 in the driver

3.16.42-rc1 review patch.  If anyone has any objections, please let me know.

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

From: Hui Wang <hui.wang@...onical.com>

commit af677166cf63c179dc2485053166e02c4aea01eb upstream.

Without this change, the HDMI/DP codec will be recognised as a
generic codec, and there is no sound when playing through this codec.

As suggested by NVidia side, after adding the new ID in the driver,
the sound playing works well.
