Message-Id: <1443114161-7965-3-git-send-email-thierry.reding@gmail.com>

Subject: [PATCH 3/6] drm/imx: Build monolithic driver
From: Thierry Reding <treding@...dia.com>
There's no use building the individual drivers as separate modules
because they are all only useful if combined into a single DRM/KMS
device.
