Subject: ASoC: soc-compress: Inherit atomicity from DAI link for Compress FE
From: Daniel Baluta <daniel.baluta@xxxxxxx>
commit 37b58becc1cee4d591024f2056d7ffa99c6089e0 upstream.
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.
Fixes: bbf7d3b1c4f4 ("ASoC: soc-pcm: align BE 'atomicity' with that of the FE")
