drm/i915: fix hotplug event bit tracking
commit 142e239849c800f9dc23f828762873073f612d3f Author: Egbert Eich <eich@suse.de> Date: Thu Apr 11 15:57:57 2013 +0200 drm/i915: Add bit field to record which pins have received HPD events (v3) added a bit field for hotplug event tracking. There ended up being three different v3 of the patch: [1], [2], and [3]. Apparently [1] was the correct one, but some frankenstein combination of the three got committed, which reversed the logic for setting the hotplug bits and misplaced a continue statement, skipping the hotplug irq storm handling altogether. This lead to broken hotplug detection, bisected to commit 321a1b3026ea194dd084cf3bda1e235b2986b0af Author: Egbert Eich <eich@suse.de> Date: Thu Apr 11 16:00:26 2013 +0200 drm/i915: Only reprobe display on encoder which has received an HPD event (v2) which uses the incorrectly set hotplug event bits. Fix the mess.
