[PATCH] iommu/ipmmu-vmsa: use devm_platform_get_and_ioremap_resource()

From: ye.xingchen
Date: Wed Feb 08 2023 - 03:06:12 EST


From: Ye Xingchen <ye.xingchen@xxxxxxxxxx>

Convert platform_get_resource(), devm_ioremap_resource() to a single
call to devm_platform_get_and_ioremap_resource(), as this is exactly
what this function does.
