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.

I am really sorry. I have already try my best to find the latest code but fails. Please give me the url or the git repository.

Sincerely thanks, Jiang
