From 848ed7d54246296f684a4b99546e20d0577aec72 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.
