I don't think it makes sense to have a "proper order" verified on
checkpatch, as some tags may appear on different places.

For instance, the custody chain was designed to have SoBs appearing
in different places:

- author(s) SoB together co-developed-by are usually the first ones;
- then patches may have been reviewed, tested, acked or passed on some
  other trees, gaining tags like tested-by, R-B, A-B, SoB, Cc;
- the subsystem maintainer will add his SoB in the end.

non-custody chain tags, like fixes, closes, reported-by...
usually comes first, but I don't think we need to enforce an specific
order.

Link, for instance, could be used on different places, with different
purposes.

At least for me, the only part that shall really follow a proper
order is the custody chain: It has to follow how the patch was handled,
from the authors at the top up to the maintainers at the bottom.

Thanks,
