If this is correct, then you should use the following "Fixes" tag instead,
which is the one that introduced the bug:

Fixes: 43d24e76b698 ("ASoC: fsl_esai: Add ESAI CPU DAI driver")

Fixes: 16bbeb2b43c3 ("ASoC: fsl_esai: Mark expected switch
fall-through")

because this didn't change any functionality.

Ok, this will be updated.

Also, you should use a simple assignment operator "=" instead of "|=" in
both cases.

The result is same for "=" and "|=", because there is "ecr = 0" in beginning of
This function.
