* BugLink was missing in cover letter:
  https://canonical-kernel-docs.readthedocs-hosted.com/en/latest/reference/patch_acceptance_criteria/#sru-cover-letter

* Bug should be marked "Invalid" for “linux (Ubuntu)” instead of “New”
  given the patches are upstream cherry-picks and will likely arrive
  automatically in Plucky or are already there.

Other than that, LGTM.
