[PATCH 13/15] ASoC: rt5682-sdw: set regcache_cache_only false before reading RT5682_DEVICE_ID

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



From: Bard Liao <yung-chuan.liao@xxxxxxxxxxxxxxx>

RT5682_DEVICE_ID is a volatile register, we can not read it in cache
only mode.

Fixes: 03f6fc6de919 ("ASoC: rt5682: Add the soundwire support")
