From 1b9faf5e66bae8428a4ccdc1447d5399d1014581 Mon Sep 17 00:00:00 2001 From: Julia Lawall Date: Sun, 8 Jul 2012 01:37:38 +0000 Subject: [PATCH] drivers/isdn/mISDN/stack.c: remove invalid reference to list iterator variable If list_for_each_entry, etc complete a traversal of the list, the iterator variable ends up pointing to an address at an offset from the list head, and not a meaningful structure. Thus this value should not be used after the end of the iterator. The dereferences are just deleted from the debugging statement. This problem was found using Coccinelle (http://coccinelle.lip6.fr/).
