Comment 22 for bug 1343543

I reverted the offending commit in the v3.16-rc5 branch and it seems to fix the problem.

Specifically, in the file drivers/gpu/drm/i915/intel_dp.c
near line 1902, under function :
 static void intel_disable_dp(struct intel_encoder *encoder)

I changed line 1912 from:
 intel_dp_sink_dpms(intel_dp, DRM_MODE_DPMS_OFF);
to:
 intel_dp_sink_dpms(intel_dp, DRM_MODE_DPMS_ON);

And that seems to fix the problem.

How do I proceed from here?
