I think snd_soc_cache_init() should return 0 rather than -EINVAL if reg_size is 0.

Yes, this fixes the issue:

--- a/sound/soc/soc-cache.c +++ b/sound/soc/soc-cache.c @@ -73,7 +73,7 @@ int snd_soc_cache_init(struct snd_soc_codec *codec) reg_size = codec_drv->reg_cache_size * codec_drv->reg_word_size;

if (!reg_size) - return -EINVAL; + return 0;

mutex_init(&codec->cache_rw_mutex);
