The hot plug function for DP appears to have been broken somewhere along the way. Without

Perhaps a discussion of why it was removed and how the apparent conflict
should be resolved?
In particular citing the commit that gutted the function and cc'ing the
author (Dave Airlie) and reviwers (you) are in order.

drm/i915: add DP 1.2 MST support (v0.7)
I'm sure this shouldn't be needed as we get short/long hotplug DP
events in the pulse handler,
not here.
Dave.
Sounds good. Looking at the HPD pulse handler, I think I can get the
necessary code in there for the non-MST case to get compliance testing
working with just the pulse handler. The short pulse will catch it
already, but I need to add code to the long pulse segment in order to
get the correct notification there.
