+Subject: drm/i915: reorder setup sequence to have irqs for output setup
+
+From: Daniel Vetter <daniel.vetter@ffwll.ch>
+
+commit 52d7ecedac3f96fb562cb482c139015372728638 upstream.
+
+Otherwise the new&shiny irq-driven gmbus and dp aux code won't work that
+well. Noticed since the dp aux code doesn't have an automatic fallback
+with a timeout (since the hw provides for that already).
+
+v2: Simple move drm_irq_install before intel_modeset_gem_init, as
+suggested by Ben Widawsky.
+
+v3: Now that interrupts are enabled before all connectors are fully
+set up, we might fall over serving a HPD interrupt while things are
+still being set up. Instead of jumping through massive hoops and
+complicating the code with a separate hpd irq enable step, simply
+block out the hotplug work item from doing anything until things are
+in place.
+
+v4: Actually, we can enable hotplug processing only after the fbdev is
+fully set up, since we call down into the fbdev from the hotplug work
+functions. So stick the hpd enabling right next to the poll helper
+initialization.
+
+v5: We need to enable irqs before intel_modeset_init, since that
+function sets up the outputs.
+
+v6: Fixup cleanup sequence, too.
