Why do you have these different paths for OF and platform? AFAIK these
days when a OF device is automatically converted into a platform
device all the struct resources are created too, so you can't you just
use platform_get_resource and devm_request_and_ioremap for both flows?
Ditto for the interrupt - platform_get_irq should work in both cases?
