A bit late, but found something: Why can't we use dev->vblank[crtc].queue
here? We reuse all the vblank infrastructure already ...

If you want pretty just add a tiny helper function

wait_queue_head_t *drm_crtc_vblank_waitqueue(struct drm_crtc *crtc)
{
return &dev->vblank[drm_crtc_index(crtc)].queue;
}

somewhere.

I feel guilty here since I've killed Akash's patch over adding a new
vblank wait queue and let yours slip through ;-) Can you please take care
of this?

Thanks, Daniel
