The above warning is not for the link. After wrapping the line, however,
checkpatch does warn the link line like below.

WARNING: Prefer a maximum 75 chars per line (possible unwrapped commit description?)
#13:
[1]: https://lore.kernel.org/damon/66131775-180b-4b9f-b7ce-61a3e077b6e6@xxxxxxxxxxxxxxxxxxx/T/#m278d3c9bbedcceaf2efa51e3dc7b40a40654e51c

But, it should be ok to just ignore the warning for the link line. So, please
wrap the line, but keep the link.


Thanks,
SJ
