There was a check for result being not NULL. But get_acl() may return NULL, or ERR_PTR, or actual pointer. The purpose of the function where current change is done is to "list ACLs only when they are available", so any error condition of get_acl() mustn't be elevated, and returning 0 there is still valid.
