From: Daniel Baluta <daniel.baluta@xxxxxxx> After commit bbf7d3b1c4f40 ("ASoC: soc-pcm: align BE 'atomicity' with that of the FE") BE and FE atomicity must match. In the case of Compress PCM there is a mismatch in atomicity between FE and BE and we get errors like this: [ 36.434566] sai1-wm8960-hifi: dpcm_be_connect: FE is atomic but BE is nonatomic, invalid configuration [ 36.444278] PCM Deep Buffer: ASoC: can't connect SAI1.OUT In order to fix this we must inherit the atomicity from DAI link associated with current PCM Compress FE.
