Subject: [PATCH 11/12] drm/vc4: move to devm_platform_ioremap_resource()
usage
Replace platform_get_resource_byname + devm_ioremap_resource
with just devm_platform_ioremap_resource()
Used Coccinelle to do this change. SmPl patch:
//rule s/(devm_)platform_get_resource_byname +
//(devm_)ioremap/devm_platform_ioremap_resource.
@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);
...+>
v2: Change the SmPl patch to work on multiple occurences of
the pattern. This also fixes the compilation error.
