+Subject: [PATCH] nvmem: bcm-ocotp: Use devm_platform_ioremap_resource()
+
+According to commit 7945f929f1a7 ("drivers: provide
+devm_platform_ioremap_resource()"), convert platform_get_resource(),
+devm_ioremap_resource() to a single call to use
+devm_platform_ioremap_resource(), as this is exactly what this function
+does.
