Dear Maintainer,

*** Reporter, please consider answering these questions, where appropriate ***

   * What led up to the situation? - Installed current version of
driver in repo (550.163.01-4), and I noticed a warning logged to dmesg
when the system was booting. nvidia_drm.modeset=1 is correctly enabled
and reports Y, but DRM permissions are revoked at runtime (error
below): WARNING: CPU: PID: ... at
nvidia-drm-dev.c:nv_drm_revoke_modeset_permission.

As a result: PRIME render offload fails, DRI_PRIME=1 glxinfo falls
back to llvmpipe, and Xorg reports Failed to load driver: nvidia-drm

This occurs even though nvidia_drm is loaded, modesetting is enabled
and NVIDIA provider appears in xrandr --listproviders


   * What exactly did you do (or not do) that was effective (or
     ineffective)? - Installing 580 straight from NVIDIAs repos fixed
this issue.
   * What was the outcome of this action? - System boots normally, and
PRIME offloading works normally.
   * What outcome did you expect instead? - N/A
   * Additional info - Other users reporting this bug here:

- NVIDIA has made the 580 version of the driver the production
version, and installing that version fixes the issue.
