This is fine for cover letter, not for the commits.

After your analysis software finds an issue you should manually analyze
what is wrong and document that to the commit message. This applies to
sparse, coccinelle or any other tool.

Tool-based commit messages are bad for commit history where as clean
description gives idea what was done (if you have to maintain a GIT
tree).

In my opinion tool is doing all the work but the part that you should do
is absent.
