[PATCH 3.11 060/131] ALSA: hda/ca0132 - Fix recording from mode id 0x8

[Luis Henriques]

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

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

From: Hsin-Yu Chao <hychao@xxxxxxxxxxxx>

commit 13c12dbe3a2ce17227f7ddef652b6a53c78fa51f upstream.

Incorrect ADC is picked in ca0132_capture_pcm_prepare(),
where it assumes multiple streams while there is one stream
per ADC. Note that ca0132_capture_pcm_cleanup() already does
the right thing.

The Chromebook Pixel has a microphone under the keyboard that
is attached to node id 0x8. Before this fix, recording would
always go to the main internal mic (node id 0x7).
