Subject: [PATCH] ASoC: stm32: sai: Add missing cleanup
Git-commit: 7506baeed8d05fc164254c64af14cfed2ac14446
Patch-mainline: v5.7-rc1
References: jsc#SLE-16518
The commit 0d6defc7e0e4 ("ASoC: stm32: sai: manage rebind issue")
converts some function calls to their non-devm equivalents. The
appropriate cleanup code was added to the remove function, but not
to the probe function. Add a call to snd_dmaengine_pcm_unregister
to compensate for the call to snd_dmaengine_pcm_register in case
of subsequent failure.
Fixes: commit 0d6defc7e0e4 ("ASoC: stm32: sai: manage rebind issue")
