Subject: [PATCH 04/59] drm/vboxvideo: Stop using drm_device->dev_private
Date: Wed, 15 Apr 2020 09:39:39 +0200	[thread overview]
Message-ID: <20200415074034.175360-5-daniel.vetter@ffwll.ch> (raw)
In-Reply-To: <20200415074034.175360-1-daniel.vetter@ffwll.ch>

We use the baseclass pattern here, so lets to the proper (and more
typesafe) upcasting.
