Subject: [PATCH] ASoC: soc-compress: Inherit atomicity from DAI link for Compress FE

From: Daniel Baluta <daniel.baluta@....com>

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")
