Thank you for your patch. There is something to discuss/improve.

Minor nits:

1. Don't use "this patch".
https://elixir.bootlin.com/linux/v5.17.1/source/Documentation/process/submitting-patches.rst#L95
2. Use subject prefix matching subsystem (git log --oneline)

3. No external references to some issue management systems, change-ids
etc. Lore link could work, but it's not relevant here, I guess.
