You are right. devm_regmap_init_mmio() returns an ERR_PTR() on error
or a valid pointer to a struct regmap on success,
so checking for NULL here is not correct.

Also, if devm_regmap_init_mmio() fails, the probe will already fail.
Therefore, I will remove the if (!afe->regmap) check here.


Best regards,
Phuc
