[PATCH 0/6] drm/xe/log: Relax location ID recognition

[Michal Wajdeczko <michal.wajdeczko@intel.com>]

Some errors reported by the VF during early probe may have improper
format as provided GT location is not correctly recognized:

 $ echo 1 | sudo tee /sys/bus/pci/devices/0000:00:02.0/sriov_numvfs
