A cover letter is not required. In cases like this where providing
additional context to the commit log is not needed, it is better to
omit it. This especially applies when there is a single patch in the
series.

If you want to add version diff info or any additional context, you
can add it after "---" in the patch itself. Example:
https://lore.kernel.org/linux-mm/20240430133138.732088-1-ryan.roberts@arm.com/.
