[PATCH] dmaengine: uniphier-mdmac: use devm_platform_ioremap_resource()
From: Masahiro Yamada <hidden>
Date: 2019-09-05 03:42:07

dmaengine, lkml
Subsystem:
arm/uniphier architecture, dma generic offload engine subsystem, the rest · Maintainers:

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.
