This patch has been added to the 3.12 stable tree. If you have any
objections, please let us know.
===============
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).
