When posting a patch fixing an issue introduced by another one,
you'll get more feedback if Cc'ing the author/reviewers of such
patch.

Also Cc'ing the maintainers also help in having your patch picked
up :) See:

https://www.qemu.org/docs/master/devel/submitting-a-patch.html#cc-the-relevant-maintainer

I've Cc'ed the corresponding developers for you.

Regards,

Phil.
