From 68eda8f59081c74a51d037cc29893bd7c9b3c2d8 Mon Sep 17 00:00:00 2001 From: Dan Carpenter Date: Sun, 8 Aug 2010 00:17:51 +0200 Subject: tomoyo: cleanup. don't store bogus pointer 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.
