Hello, the media CI robot complained to me privately (not to the list)
with the following error:

  ERROR: Commit a1e2940458853d00c178c842c889e4ae3ef5eaec NOT found in
  the stable tree, but stable@...r.kernel.org is in Cc:

However, the Fixes: tag references the commit hash in master, but the
commit has a different hash in the stable branches. This is my first
time running into such an issue and I'm not sure what to do about it?

Thanks,
Thorsten
