This fixes the warning:
--- a/sound/soc/fsl/fsl_ssi.c
+++ b/sound/soc/fsl/fsl_ssi.c
@@ -180,7 +180,6 @@ static const struct regmap_config fsl_ssi_regconfig = {
.volatile_reg = fsl_ssi_volatile_reg,
.precious_reg = fsl_ssi_precious_reg,
.writeable_reg = fsl_ssi_writeable_reg,
- .cache_type = REGCACHE_RBTREE,
};
Is this the correct fix?
