Subject[PATCH 5.8 051/118] ASoC: core: Do not cleanup uninitialized dais on soc_pcm_open failure
Date
From: Cezary Rojewski <cezary.rojewski@intel.com>

[ Upstream commit 20244b2a8a8728c63233d33146e007dcacbcc5c4 ]

Introduce for_each_rtd_dais_rollback macro which behaves exactly like
for_each_codec_dais_rollback and its cpu_dais equivalent but for all
dais instead.

Use newly added macro to fix soc_pcm_open error path and prevent
uninitialized dais from being cleaned-up.
