Prevent the VF from attempting to update the GuC reset policy when
changing the wedged mode, as this operation is not supported on VFs.
Additionally, validate the wedged_mode module parameter input, update
the internal wedged.mode state only on success, and allow setting
wedged_mode=2 only in debug builds if running as PF.
Lukasz Laguna (4):
drm/xe: Don't update wedged mode in case of an error
drm/xe: Validate wedged_mode modparam input
drm/xe/vf: Disallow setting wedged_mode=2
drm/xe/pf: Allow wedged_mode=2 only in debug config
