Subject: [PATCH 2/2] drm/omap: simplify getting .driver_data
Date: Tue, 19 Mar 2019 17:36:29 +0100	[thread overview]
Message-ID: <20190319163629.30660-2-wsa+renesas@sang-engineering.com> (raw)
In-Reply-To: <20190319163629.30660-1-wsa+renesas@sang-engineering.com>

We should get 'driver_data' 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.
