Hello,

As far as I can tell from the mails that you have provided, those
patches replace devm_request_mem_region(), followed by devm_ioremap()
with devm_request_and_ioremap().
What this patch attempts to do is replace devm_request_and_ioremap()
with the newly introduced devm_ioremap_resource(), for the reasons
expressed in the patch body.

Thanks,
Silviu
