Hi Jakub,
This patchset is not added the original warning. Warning got added due to a commit [1].
Its not related to subfunction.
It will be fixed regardless of this patchset as posted in [2].

[1] 2a2970891647 ("net/mlx5: Add sample offload hardware bits and structures")
[2] https://lore.kernel.org/netdev/20201213123620.GC5005@unreal/
