In the drm world we include the revision notes in the changelog.
So I did this when I applied it to drm-misc-next.

Fixed a few trivial checkpatch warnings about indent too.
There was a few too-long-lines warnings that I ignored. Fixing them
would have hurt readability.

I assume you will maintain this driver onwards from now.
Please request drm-misc commit rights (see
https://www.freedesktop.org/wiki/AccountRequests/)
You will need a legacy SSH account.

And you should familiarize yourself with the maintainer-tools:
https://drm.pages.freedesktop.org/maintainer-tools/index.html

For my use I use "dim update-branches; dim apply; dim push
So only a small subset i needed for simple use.
