Oh, thanks. I'm flattered :)

Yes, you are right. Sorry for missing this detail when suggesting an
example to convert to devm_*. devm_ioremap_resource should be favoured
over devm_ioremap.

This is correct and preferred.

BTW I don't care much about splitting up the patch as long as the commit

Thanks Rickard for picking up the task, and thanks Jingoo for reviewing.
