From: Julia Lawall <Julia.Lawall@xxxxxxx> 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/).
