Didn't a big patch come through recently converting all usages of 
devm_request_and_ioremap() to another function (I forget the name) that 
does its own error reporting and returns an ERR_PTR value?

(Checks the mailing list archive...)  Ah, here it is:

And the new function is devm_ioremap_resource().  We should avoid 
adding new usages of an old interface.
