Matthias Reichl fea8806444 regmap: fix bogus error on regcache_sync success ... Since commit 0ec7731655 ("regmap: Ensure range selector registers are updated after cache sync") opening pcm512x based soundcards fail with EINVAL and dmesg shows sync cache and pm_runtime_get errors: [ 228.794676] pcm512x 1-004c: Failed to sync cache: -22 [ 228.794740] pcm512x 1-004c: ASoC: error at snd_soc_pcm_component_pm_runtime_get on pcm512x.1-004c: -22 This is caused by the cache check result leaking out into the regcache_sync return value. Fix this by making the check local-only, as the comment above the regcache_read call states a non-zero return value means there's nothing to do so the return value should not be altered.
