Thanks. To pass the checkpatch CI, you need to reword your commit to add a description and the signature. To do so, you can run the following:

$ git commit --amend -s
# This will open your default editor and there you'll see the signed-off-by line.
# Add a commit description below the commit title.

$ git push -f  # Update the remote repo
