Current BDW virtual display port is initialized as PORT_B, so need to use same port for VFIO EDID region, otherwise invalid EDID blob pointer is assigned which caused kernel null pointer reference. We might evaluate actual display hotplug for BDW to make this function work as expected, anyway this is always required to be fixed first.
