Revision e1f48ee58a90ddf84f514334b5d395a358596492 authored by Imre Deak on 02 November 2012, 11:30:48 UTC, committed by Inki Dae on 29 November 2012, 11:30:33 UTC 
drm/exynos: call drm_vblank_put for each queued flip event
 
It's guaranteed that for each event on pageflip_event_list we have
called drm_vblank_get() - see exynos_drm_crtc_page_flip() - so checking
for this is redundant.

Also we need to call drm_vblank_put() for each event on the list, not
only once, otherwise we'd leak vblank references if there are multiple
events on the list.
