EDAC/dmc520: Use devm_platform_ioremap_resource()

[Patch v1] EDAC/dmc520: Use devm_platform_ioremap_resource()

Posted by Jai Arora 1 year, 7 months ago

platform_get_resource() and devm_ioremap_resource() are wrapped up in the
devm_platform_ioremap_resource() helper. Use the helper and get rid of the
local variable for struct resource *. We now have a function call less.
