Minor correction, the above commit from the bisect is the actual fix to the
null pointer/black screen issue.

    drm/i915: Move long hpd handling into the hotplug work

@Kirill/Jani can you please verify this at your end? 

Reverting this commit from today's nightly as well as the before/after of Oct 3
by git hard --reset 27d4efc5591a I obtain the same result.
