If domain is NULL then &domain->list is a bogus address. Let's leave head->r.domain NULL instead of saving an unusable pointer. This is just a cleanup. The current code always checks head->r.eof before dereferencing head->r.domain. Signed-off-by: Dan Carpenter <error27@gmail.com> Acked-by: Tetsuo Handa <penguin-kernel@I-love.SAKURA.ne.jp>
