Yes, if the changes are reasonably small and the code has already
undergone significant review.

Although the mm-new branch is quite speculative/early so I guess this
is less important there.

Adding a sprinkle of -fix patches can be a pain all round, so nowadays
if someone sends a replacement series I'll generate and send a
what-you-changed-since-last-time diff.  So

- we can check that the diff matches the changelogged updates
- reviewers don't have to re-review everything
- the author can eyeball it and think "yup, I meant to change that".

I believe this series is due for quite a few updates so a full v6
resend series would be appropriate.  I'll generate the
how-you-changed-mm.git email from that.
