Quick grep says a lot don't have it or at least not implemented - they
use drm_vblank_count. Thinking about this, should we use that as a
signal to also set

Calling vblank_disable_fn() will cause that function to no-op
if !dev->vblank_disable_allowed for some kms drivers, e.g.,

vblank irq fires and calls into drm_handle_vblank() after
