--- Comment #19 from Anshuman Gupta <anshuman.gupta at intel.com> ---
This issue is only has seen with CI H/W fi-skl-6770hq, this CI H/W uses LSPCON.
https://intel-gfx-ci.01.org/hardware/fi-skl-6770hq/i915_display_info.txt tells
that DP "branch device present: yes" and device type is HDMI.
Probable root cause is due to DP-1 connector is disconnected when IGT
module-reload test probe DP1 connector modes, which resulted  in  mismatch of 
DP1 connector physical width.
