Derek, given the upstream bug you noted is scoped to completely
different hardware, you would be better off filing a new one, versus
attempting to expand its scope.

Title:
8086:0a16 displayport MST external monitors don't return from sleep
mode
Status in Linux:
New
Status in linux package in Ubuntu:
Triaged
Bug description:
When displays go to sleep, upon return from sleep the two monitors
attached to a belkin mini displayport to 2x HDMI, do not return from
sleep. This results in part of the desktop being inaccessible, until
the external displays are unplugged, and then plugged back in.
Sometimes, Xorg will also back down to one monitor. The data
accompanying this report is for an instance where the power save mode
caused Xorg to drop to the primary monitor only.
This is on Ubuntu 15.10 on a Dell XPS 13 (9333) with integrated intel
HD 4400 graphics. There are two external monitors connected by HDMI to
a belkin DP-MST adapter which connects to the mini-displayport. A
single-HDMI-to-mini-displayport belkin adapter works as expected
(coming out of power save).
xserver-xorg-video-intel:
Installed: 2:2.99.917+git20150808-0ubuntu4
Expected behavior: Displays go to sleep, and upon returning all
displays are still present and all wake.
