ASoC: Mediatek: MT8183: enable dev runtime suspend and resume (5463eb5c) · Commits · 戴 / test

System suspend will power off audio, so we need regcache sync when system resume. Remove pm_runtime_get_sync in dev probe and pm_runtime_put_sync in dev remove.So that audio dev can triggle runitme suspend and resume. Signed-off-by:
