devm_request_and_ioremap will already print a error messages on it's own if
something goes wrong. So strictly speaking this one is redundant, but I don't
think it is necessary to do a resend just for this, maybe you can remove the
extra dev_err when you apply the patch.

Thanks for pointing that out.  I will get rid of the messages in the 
future.  That seems easier than figuring out how to adapt the message to 
the new function.
