Static analysis reports this problem

return err;
^~~~~~~~~~

err is only set if there is some work to do. Because the loop returns
immediately on an error, if all the work was done, a 0 would be returned.
Instead of checking the unlikely case that there was no work to do,
change the return of err to 0.
