Re: [PATCH v2] ASoC: codecs: Check for error pointer after calling devm_regmap_init_mmio

Since the possible failure of the devm_regmap_init_mmio(), it will return error pointer and be assigned to the regmap. Then the error pointer will be dereferenced. For example rx->regmap will be used in rx_macro_mclk_enable(). Therefore, it should be better to check it.

This doesn't apply against current code, please check and resend.
