Subject: [PATCH 1/6] dmaengine: at_hdmac: simplify getting .drvdata
Date: Sun, 22 Apr 2018 11:14:09 +0200 [thread overview]
Message-ID: <20180422091415.7587-2-wsa+renesas@sang-engineering.com> (raw)
In-Reply-To: <20180422091415.7587-1-wsa+renesas@sang-engineering.com>
We should get drvdata from struct device directly. Going via
platform_device is an unneeded step back and forth.
