-Subject: [PATCH 575/806] drm/vc4: Disable V3D interactions if the v3d
- component didn't probe.
-
-One might want to use the VC4 display stack without using Mesa.
-Similar to the debugfs fixes for not having all of the possible
-display bits enabled, make sure you can't oops in vc4 if v3d isn't
-enabled.
