Subject: [PATCH 03/61] auxdisplay: simplify getting .drvdata
Date:   Thu, 19 Apr 2018 16:05:33 +0200
Message-Id: <20180419140641.27926-4-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.
