From mboxrd@z Thu Jan 1 00:00:00 1970 From: wsa+renesas@sang-engineering.com (Wolfram Sang) Date: Sun, 22 Apr 2018 11:14:10 +0200 Subject: [PATCH 2/6] dmaengine: at_xdmac: simplify getting .drvdata In-Reply-To: <20180422091415.7587-1-wsa+renesas@sang-engineering.com> References: <20180422091415.7587-1-wsa+renesas@sang-engineering.com> Message-ID: <20180422091415.7587-3-wsa+renesas@sang-engineering.com> To: linux-arm-kernel@lists.infradead.org List-Id: linux-arm-kernel.lists.infradead.org We should get drvdata from struct device directly. Going via platform_device is an unneeded step back and forth. Signed-off-by: Wolfram Sang --- Build tested only. buildbot is happy.
