Merge tag 'asoc-fix-v4.9-rc3' of git://git.kernel.org/pub/scm/linux/kernel/git/broonie/sound into for-linus
ASoC: Fixes for v4.9 The most important fix in here is a change which removes the #error making the topology API unusable as-is since we have recently discovered some production uses on Chromebooks so need to acknowledge that what we've got there now is an ABI. There's also a very big batch of driver specific fixes here which have kept on being delayed due to more arriving so the update is another of these bigger than I would like ones. There is one especially big one in there, for the Qualcomm code which fixes simultaneous playback and capture which was broken during the merge window. The diff for that is large because it moves blocks of code to different functions but it's functionally fairly simple and if it breaks it should have been very obvious in testing.
