Mark Brown cab648a436 ASoC: Updates for v3.15 
This is mostly a few additional fixes from Lars-Peter, a new driver and
 cleaning up a git failure with merging the Intel branch (combined with
 an xargs failure to pay attention to error codes).  The history lists a
 bunch of additional commits for the branch but the content of those
 commits is actually present already but not recorded in history due to
 git failing.  Unfortunately xargs is used in the merge script and it
 doesn't do a good job of noticing errors from the commands it invokes.
