hmm, I never was good at selling :o

but I'll try anyways: it shall make the code smaller and easier to
read/understand.

does that count ?

Ok, I wasn't aware of that. Yes, I missed to read the code of that
function carefully and didn't expect that it does more than just a dumb
wrapper around dev_ioremap() that picks out the params from struct
resource.

OTOH, the name, IMHO, is a bit misleading. Any chance of ever changing
it to a more clear name (eg. devm_request_and_ioremap_resource()) ?
