From aae2856c35f782d01d54ee454441af75181471d0 Mon Sep 17 00:00:00 2001 From: Emil Velikov Date: Mon, 27 May 2019 09:17:40 +0100 Subject: [PATCH] drm/virtio: drop DRM_AUTH usage from the driver The authentication can be circumvented, by design, by using the render node. From the driver POV there is no distinction between primary and render nodes, thus we can drop the token.
