-Subject: [PATCH] drm/vc4: Enable/Disable vblanks properly in crtc en/disable.
-
-Add missing drm_crtc_vblank_on/off() calls so vblank irq
-handling/updating/timestamping never runs with a crtc shut down
-or during its shutdown/startup, as that causes large jumps in
-vblank count and trouble for compositors.
