Subject: drm/vgem: drop DRM_AUTH usage from the driver
Git-commit: 0a0b65d8eae3eb25dde57f72596b7a7c81a126fa
Patch-mainline: v5.4-rc1
References: bsc#1152472
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.
