Subject: [PATCH 1/2] drm/vram: store dumb bo dimensions.
Date:   Wed, 26 Jun 2019 08:55:50 +0200
Message-Id: <20190626065551.12956-2-kraxel@redhat.com>
In-Reply-To: <20190626065551.12956-1-kraxel@redhat.com>
References: <20190626065551.12956-1-kraxel@redhat.com>
Sender: linux-kernel-owner@vger.kernel.org
Precedence: bulk

Store width and height of the bo.  Needed in case userspace
sets up a framebuffer with fb->width != bo->width..
