Subject: checkpatch: use a list of "link" tags
Date: Mon, 03 Apr 2023 18:23:48 +0200

The following commit will allow the use of a similar "link" tag.

Because there is a possibility that other similar tags will be added in
the future and to reduce the number of places where the code will be
modified to allow this new tag, a list with all these "link" tags is now
used.

Two variables are created from it: one to search for such tags and one to
print all tags in a warning message.
