- Subject: [PATCH] drivers: provide devm_platform_ioremap_resource()
- There are currently 1200+ instances of using platform_get_resource()
- and devm_ioremap_resource() together in the kernel tree.
- This patch wraps these two calls in a single helper. Thanks to that
- we don't have to declare a local variable for struct resource * and can
- omit the redundant argument for resource type. We also have one
- function call less.
