I see your point. I would still like to get rid of the duplicated code
(then it can't be forgotten as well). Maybe I should have named the
function something alike devm_check_and_request_and_ioremap()? Then I
could have also introduced a similar function for requesting irq. Will
think about this a bit more. Thanks for updating your patch!
