Replace error_setg(&err, ...); error_propagate(errp, err);
by error_setg(errp, ...); Related pattern: if (...) { error_setg(&err, ...); goto out; } ... out: error_propagate(errp, err); return; When all paths to label out are that way, replace by if (...) { error_setg(errp, ...); return; } and delete the label along with the error_propagate(). When we have at most one other path that actually needs to propagate, and maybe one at the end that where propagation is unnecessary, e.g. foo(..., &err); if (err) { goto out; } ... bar(..., &err); out: error_propagate(errp, err); return; move the error_propagate() to where it's needed, like if (...) { foo(..., &err); error_propagate(errp, err); return; } ... bar(..., errp); return; and transform the error_setg() as above. Bonus: the elimination of gotos will make later patches in this series easier to review.
