Message-ID: <1350980483-4992-1-git-send-email-zhanghonghui@huawei.com> Date: Tue, 23 Oct 2012 16:21:23 +0800 From: <zhanghonghui@...wei.com> To: <davem@...emloft.net> CC: <netdev@...r.kernel.org>, <linux-kernel@...r.kernel.org>, <lizefan@...wei.com>, <edumazet@...gle.com>, Hans Zhang <zhanghonghui@...wei.com> Subject: [PATCH] netlink: cleanup the unnecessary return value check From: Hans Zhang <zhanghonghui@...wei.com> It's no needed to check the return value of tab since the NULL situation has been handled already, and the rtnl_msg_handlers[PF_UNSPEC] has been initialized as non-NULL during the rtnetlink_init().
