Or something similar.  Yes, error_report() is better than fprintf.  But
error_report() is only good if you are directly interacting with the
user; if this code can be reached via a QMP monitor command, it would be
better to adjust signatures and propagate an Error **errp back to the
caller, so that the caller knows how best to report it.  But that's more
plumbing effort, so it doesn't necessarily have to be you doing the
work, nor this series.
