Anusha Srivatsa Jan. 28, 2025, 10:29 p.m. UTC 
Replace platform_get_resource + devm_ioremap_resource
with just devm_platform_ioremap_resource()

Used Coccinelle to do this change. SmPl patch:
@rule_1@
identifier res;
expression ioremap_res;
identifier pdev;
@@
-struct resource *res;
...
-res = platform_get_resource(pdev,...);
-ioremap_res = devm_ioremap_resource(...);
+ioremap_res = devm_platform_ioremap_resource(pdev,0);
