Unfortunately we didn't have time to review the patch-set yet,
but keep in mind that LTP AI Reviewer approval is not a certainty
that patches will be merged. This only means that agent didn't spot
major issues :-)

At the end, one of the maintainer will need to approve the review
of the agent and sending new feedbacks.
