Hi Gustavo
if (s->event) {
+ struct drm_crtc *crtc = drm_crtc_find(dev, s->crtc);
+
I don't think this would work. s->crtc is a nouveau internal display
pipe index, not a drm mode object id, so i don't think drm_crtc_find()
will do what you need. Also it takes a mutex, which might_sleep() and i
think nouveau_finish_page_flip gets called from irq context and holds a
spin_lock_irqsave, so would end badly.
You'd probably have to extend struct nouveau_page_flip_state to carry
around a reference to the required drm_crtc, set up in
nouveau_crtc_page_flip().
