--- Comment #11 from Stanislav Lisovskiy <stanislav.lisovskiy at intel.com> ---
Looks drm_wait_one_vblank fails because it is being called from
intel_display_suspend/resume, when vblank interrupts are not going to happen
because system is in the suspended state. This causes a time out if were
unlucky not to have any vblank events accumulated in the queue. 
I guess the fix should be that we check if we are not in suspended state in
intel_pre_plane_update, otherwise it makes no sense to wait for it.

I have done a small fix, so I just need to verify it now.
