If Samsung are going to be doing their upstreaming stuff it may make
sense to merge this via ASoC since I anticipate some changes there, but
on the other hand that seems to have ground to a halt and the merge may
well go smoothly anyway.  My standard answer here would be putting the
patch on a branch by itself so if there are any issues it can be merged
into both trees to avoid the merge issues.
