The correct SPDX identifier for the 'GNU General Public License v2.0 or
later' is GPL-2.0-or-later.

Checkpatch.pl uses the misspelled words from spelling.txt both as keys of a
hash and as part of a regular expression. For usage in the regular
expression special characters like the plus sign need to be escaped.

I think this unnecessary as there's a separate script
to check the appropriate SPDX uses treewide and there
isn't a single existing use of "gpl-2.0+' in the tree.

Hello Joe,

In next-20241213 I find 5143 occurrences with

git grep -ni 'gpl-2\.0+' | wc -l

e.g.

Documentation/bpf/prog_lsm.rst:1:.. SPDX-License-Identifier: GPL-2.0+
drivers/ata/sata_rcar.c:1:// SPDX-License-Identifier: GPL-2.0+

Some additions are quite recent:

$ git diff HEAD~100 | grep -i 'gpl-2\.0+' | wc -l
63

Best regards

Heinrich

So no uses of 'gpl-2.0+' but many of 'GPL-2.0+'

And perhaps read this:
