Subject: [PATCH v3 3/4] dmaengine: rcar-dmac: Use devm_platform_ioremap_resource()
Date: Mon, 9 Sep 2019 15:34:51 +0900 [thread overview]
Message-ID: <1568010892-17606-4-git-send-email-yoshihiro.shimoda.uh@renesas.com> (raw)
In-Reply-To: <1568010892-17606-1-git-send-email-yoshihiro.shimoda.uh@renesas.com>
This patch uses devm_platform_ioremap_resource() instead of
using platform_get_resource() and devm_ioremap_resource() together
to simplify.
