No, that was not my suggestion. My suggestion was to separate
this whole 'else if' branch:

... into a helper function - if that improves the code. Your
patch does early_ioremap, iounmap then ioremap and iounmap -
quite pointlessly.
You should resist cleanup suggestions that make the code worse,
even if it comes from a maintainer :-)
