Subject: [PATCH 2/6] dmaengine: at_xdmac: simplify getting .drvdata
Date: Sun, 22 Apr 2018 11:14:10 +0200	[thread overview]
Message-ID: <20180422091415.7587-3-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.

Signed-off-by: Wolfram Sang <wsa+renesas@sang-engineering.com>

Build tested only. buildbot is happy. Please apply to your tree directly.
