Thanks for your patch, but Stefano sent the same fix 2 weeks ago:
https://www.mail-archive.com/qemu-devel@nongnu.org/msg798279.html

It should be merged once the development tree opens again (we are
now 'freezed' before the v6.0.0 release).

You might want to send your Review-by or Tested-by tag to Stefano's
patch.

Regards,

Phil.
