Thanks for sharing this information, still can't reproduce though:

"""

Anyway, I ran some tests on the patch and don't see any regressions.
One small issue though, the script check-git-log.sh is failing:
"""
./devtools/check-git-log.sh -1
Wrong headline prefix:
        net/mlx5: fix possible building error
"""
You could use common/mlx5 instead of net/mlx5.
