-Subject: [PATCH 119/806] drm/vc4: Fix warning about vblank interrupts before
- DRM core is ready.
-
-The SMICS interrupt fires continuously, but since it's 1/100 the rate
-of the USB interrupts, we don't really need a way to turn it off.  We
-do need to make sure that we don't tell DRM about it until DRM has
-asked for the interrupt at least once, because otherwise it will throw
-a warning at boot time.
