However,\nthe display may also be disabled via fuses, detected at a later time in\nintel_display_device_info_runtime_init().\n\nIn this case, the xe driver does for_each_intel_crtc() on uninitialized\nmode config in xe_display_flush_cleanup_work(), leading to a NULL\npointer dereference, and generally calls display code with display info\ncleared.\n\nCheck for intel_display_device_present() after\nintel_display_device_info_runtime_init(), and reset\nxe->info.probe_display as necessary.
