the patch looks good to me, the commit message doesn't explain the
reason for the change. It can be written like:

"Previously cleanup() function was called under the out label for both
fatal errors (ret < 0) and warnings.  Now that cleanup() function is
removed, the out label is no longer required. Remove it and return
immediately for the fatal errors with ret as return code and 0 for
warnings."
