Use devm_ioremap_resource().

Error messages are already printed by devm_request_and_ioremap() ordevm_ioremap_resource().

-EADDRNOTAVAIL is the right code for devm_request_and_ioremap().
This is the first time that I read this, lib/devres.c internal returns -ENOMEM when an ioremap() call fails
What if the other call fails?
(see devm_ioremap_resource), -EADDRNOTAVAIL really is for networking matter, this is not.
Just see the comment accompanying devm_request_and_ioremap(). WBR, Sergei
