From 09e7c61feeeabac3dd983c11aca49b23155fff80 Mon Sep 17 00:00:00 2001
From: Dirk Hohndel <dirk@hohndel.org>
Date: Tue, 20 May 2014 06:37:19 +0900
Subject: Consistently use for_each_dive (and use it correctly)

The way the macro is written there is no need to test the dive against
NULL before dereferencing.
