Subject: [PATCH 00/14] drm: Move to using devm_platform_ioremap_resource
Start replacing the below occurences with the newer API:
- (devm_)platform_get_resource + devm_ioremap_resource
- (devm_)platform_get_resource + (devm_)ioremap
- platform_get_resource_byname + devm_ioremap
Move all these occurences to uses devm_platform_ioremap_resource
instead.
Address a TODO item in the GPU section.
Used Coccinelle to make the code changes.Semantic patch:
//First Case
//rule s/platform_get_resource + devm_ioremap_resource/devm_platform_ioremap_resource
@rule_1@
identifier res;
expression ioremap_res;

-struct resource *res;
...
-res = platform_get_resource(pdev,...);
-ioremap_res = devm_ioremap_resource(...);
+ioremap_res = devm_platform_ioremap_resource(pdev,0);
//Second case
