[PATCH 00/19] ASoC: codecs: propagate regcache_sync() failures

[Pengpeng Hou]

Several ASoC codec resume and reattach paths replay cached register
state with regcache_sync() after power loss, reset, runtime resume, or
SoundWire reattach. These paths currently drop regcache_sync() failures
and can report success even when cached register state was not written
back to hardware.

Propagate regcache_sync() failures from the reviewed paths and restore
cache-only/dirty state or unwind resources before returning errors. Most
patches are local resume-path error propagation. Four patches also close
failure-path issues that were held during earlier review: rt1320-sdw
restores both regmaps, rt5682-sdw restores first-init cache state,
max98396 unwinds supplies acquired during resume, and max98090 is limited
to the runtime-resume path with the stronger paired suspend/resume proof.

This series is source-audited only. I did not test on the affected
hardware.
