Sorry, I can't follow you anymore. Do you still see a problem with the patch
as it is, and if yes why?

We never ever modify reg_defaults of the reg_config we only ever modify the
reg_defaults of the regmap struct which is always runtime allocated. In the
case the config contains reg_defaults it is kmemdup'd into the reg_defaults
of the regmap struct.
