Dear Jani Nikula
Thank for your answer.
I'm sorry. I forget CHris' requests.
About Chris' requests.I try it about half a year before.The HDMI's connection
being reported correctly when I unplug HDMI and replug HDMI on first time(drm
and i915 debug mode to be opened).But when I unplug HDMI and replug HDMI on
second time,it don't report any kernel message.The driver already enter
power-save mode and cann't wake it up in any way.

Anyway, I only want to HDMI can hotpulg.So I remove "enter power-save"
function.This change not affect the performance of my system.
But the HDMI's hotplug issue may be our hardware design issues or BIOS
issues.I'm not going to try to pursue it any furthe because I have not enough
time.

Thank for your help.
