Message-Id: <1341747464-1772-6-git-send-email-Julia.Lawall@lip6.fr> Date: Sun, 8 Jul 2012 13:37:42 +0200 From: Julia Lawall <Julia.Lawall@...6.fr> To: linux-kernel@...r.kernel.org Cc: kernel-janitors@...r.kernel.org Subject: [PATCH 5/7] drivers/iommu/tegra-smmu.c: remove invalid reference to list iterator variable From: Julia Lawall <Julia.Lawall@...6.fr> 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. Replace c->dev by dev, which is the value that c->dev has been compared to. This problem was found using Coccinelle (http://coccinelle.lip6.fr/).
