From: Julia Lawall Date: Sun, 8 Jul 2012 01:37:43 +0000 (+0000) Subject: drivers/net/ethernet/broadcom/cnic.c: remove invalid reference to list iterator variable X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=022f09784b85396b4ceba954ce28e50de4882281;p=GitHub%2Fexynos8895%2Fandroid_kernel_samsung_universal8895.git drivers/net/ethernet/broadcom/cnic.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. There does not seem to be a meaningful value to provide to netdev_warn. Replace with pr_warn, since pr_err is used elsewhere. This problem was found using Coccinelle (http://coccinelle.lip6.fr/). Signed-off-by: Julia Lawall Signed-off-by: David S.
