Generally we prefer fix-patches, sent in reply to the patch being altered and
sent by the series author.

Sending a patch with a Fixes: tag is never the correct way to fixup a patch
unless they're upstream or unchangeably-bound-for-upstream with a commit hash
that will be the same in Linus's tree.

You can by all means suggest a patch to an author by replying to the broken
patch, but then it's up to them whether to take it. Also then the courteous way
is to raise the issue in that reply and say something like 'it seems that the
below fixes the issue, can you check it?' or something like this.

But the correct course is to the respond to the series in all cases like this.

Thanks, Lorenzo
