Bug#1042517: Info received (Bug#1042517: Acknowledgement (i915: oops for NULL pointer dereference on Intel HD Graphics P4000))

[Mad Horse <equu@openmail.cc>]

Further inspection shows that this oops is caused by 
intel_display_device_probe() returning NULL in 
intel_device_info_driver_create() when Intel HD Graphics P4000 
(PCI:8086:016a) is probed, which is further caused by 
INTEL_IVB_Q_IDS(NULL) (struct { u32 devid; const struct 
intel_display_device_info *info;}{ 0x16a, NULL}) in 
drivers/gpu/drm/i915/display/intel_display_device.c being erroneously 
matched against Intel HD Graphics P4000.
