+Subject: [PATCH] drm/vc4: Make sure that vblank waits work without v3d
+ loaded.
+
+This flag exists to protect legacy drivers, but when vc4's v3d doesn't
+probe, it doesn't get set up by vc4_v3d.c's call of drm_irq_install.
+This resulted in applications running as fast as possible, and laggy
+performance from compton as it had to wait for the latest rendering by
+the application for its presentation.
