Hi; thanks for this patch. Unfortunately we can't accept it
without a Signed-off-by: line from you (which tells us that you're
OK for it to be contributed to QEMU under our usual license:
for more details see:
https://www.qemu.org/docs/master/devel/submitting-a-patch.html#patch-emails-must-include-a-signed-off-by-line

Could you also provide a commit message explaining the reason
for the change?

(The code changes themselves seem sensible; I would use "break" rather
than "return", personally, but the effect is the same.)

thanks
