Subject: checkpatch: check for misuse of the link tags
Date: Mon, 03 Apr 2023 18:23:50 +0200

"Link:" and "Closes:" tags have to be used with public URLs.

It is difficult to make sure the link is public but at least we can verify
the tag is followed by 'http(s)://'.

With that, we avoid such a tag that is not allowed [1]:

  Closes: <number>

Now that we check the "link" tags are followed by a URL, we can relax the
check linked to "Reported-by being followed by a link tag" to only verify
if a "link" tag is present after the "Reported-by" one.
