Subject: [PATCH] dmaengine: uniphier-mdmac: use devm_platform_ioremap_resource()
Date: Thu, 5 Sep 2019 12:41:33 +0900 [thread overview]
Message-ID: <20190905034133.29514-1-yamada.masahiro@socionext.com> (raw)
Replace the chain of platform_get_resource() and devm_ioremap_resource()
with devm_platform_ioremap_resource().
This allows to remove the local variable for (struct resource *), and
have one function call less.
