Subject: [PATCH 04/18] drm/arc: Stop using drm_device->dev_private
Date: Fri, 17 Jul 2020 11:04:16 +0200 [thread overview]
Message-ID: <20200717090430.1146256-4-daniel.vetter@ffwll.ch> (raw)
In-Reply-To: <20200717090430.1146256-1-daniel.vetter@ffwll.ch>
Upcasting using a container_of macro is more typesafe, faster and
easier for the compiler to optimize.
