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>

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.

This way it is possible to limit 're'-detect() of displays to connectors
which have received an HPD event.

v2: Reordered drm_i915_private: Move hpd_event_bits to hpd state tracking.
v3: Fixed merge conflicts with previous patches.
