Subject: [PATCH 09/61] dmaengine: qcom: simplify getting .drvdata
Date:   Thu, 19 Apr 2018 16:05:39 +0200
Message-Id: <20180419140641.27926-10-wsa+renesas@sang-engineering.com>
In-Reply-To: <20180419140641.27926-1-wsa+renesas@sang-engineering.com>

Precedence: bulk

We should get drvdata from struct device directly. Going via
platform_device is an unneeded step back and forth.
