Seems that Antonio Argenziano (user aargenzi) has been granted /git/drm-intel.git access in error. I don't know who this is, and he's never contributed to the project AFAICT. Please revoke access.
I'll emphasize that this is only about the i915 kernel part. Antonio seems to be active in igt, and that access, if any, is fine.
Sorry, there must have been a miscommunication I think. Have removed him from the drm-intel group now, but the account is still active for igt.
