Subject: Revert "drm/i915: Exit cherryview_irq_handler() after one pass"
From: Greg Kroah-Hartman <gregkh@xxxxxxxxxxxxxxxxxxx>
This reverts commit 9dbaab56ac09f07a73fe83bf69bec3e31060080a.
Turns out it was a bad idea and was fixed up "properly" in 4.7 but those
patches are too big to put into 4.6, so let's just revert it for now.
