In DAI ops, accesses to the native cluster (of the DAI), and to data of clusters related to it by a DPCM frontend-backend link, should have been synchronized by the 'pcm_mutex' lock at ASoC level.
What is not covered are the 'port_driver' accesses on foreign clusters to which the current cluster has no a priori relation, so fill in locking for that. (This should only matter in bizarre configurations of sharing one MCA peripheral between ASoC cards.)
This also looks good.
