Subject: [PATCH] checkpatch: fix an issue regarding the git commit description style test
Date:   Wed, 14 Jul 2021 04:26:07 -0400
Message-Id: <20210714082608.28918-1-someguy@effective-light.com>

If we consider the output of the following command:

$ git shortlog | grep '"' | wc -l
14185

It becomes apparent that quite a number of commits have titles that,
contain at least one quotation mark and if you attempt to refer to those
commits in a new patch, checkpatch throws a false positive. This is
because, checkpatch disallows the use of quotation marks in commit titles,
only when referring to those commits in commit descriptions.
