[PATCH 05/14] drm/meson: move to devm_platform_ioremap_resource() usage

[Anusha Srivatsa]

Replace platform_get_resource_byname + devm_ioremap
with just devm_platform_ioremap_resource()

Used Coccinelle to do this change. SmPl patch:
@rule_3@
identifier res;
expression ioremap;
identifier pdev;
constant mem;
expression name;
@@
-struct resource *res;
...
-res = platform_get_resource_byname(pdev,mem,name);
<...
-if (!res) {
-...
-}
...>
-ioremap = devm_ioremap(...);
+ioremap = devm_platform_ioremap_resource_byname(pdev,name);
