[Intel-gfx] [PATCH maintainer-tools v2] dim: Resist committing patches that modify files outside of i915

[Joonas Lahtinen]

If committing to drm-intel-next-queued branch, require the committer
to be aware that they are committing outside of drm/i915 maintenance
scope.

v2:
- Do not use warn_or_fail (Jani)
- Only apply to drm-intel-next-queued branch (Daniel)
