Intel GFX pre-merge CI was not triggered for this submission.

Patchwork validation failed with:
"Address 'runyu.xiao@xxxxxxxxxx' is not on the allowlist, which prevents CI from being triggered for this patch."

I have already contacted i915-ci-infra@xxxxxxxxxxxxxxxxxxxxx to request allowlisting for this address.

Sorry for the confusion.
