Message-ID: <CAPgLHd9GYYu21FhiKAr2MvmYtWbL=85-E0EzJmiJm6cDDp=WcA@mail.gmail.com> Date: Tue, 25 Sep 2012 12:29:35 +0800 From: Wei Yongjun <weiyj.lk@...il.com> To: jpirko@...hat.com Cc: yongjun_wei@...ndmicro.com.cn, netdev@...r.kernel.org Subject: [PATCH] team: fix return value check From: Wei Yongjun <yongjun_wei@...ndmicro.com.cn> In case of error, the function genlmsg_put() returns NULL pointer not ERR_PTR(). The IS_ERR() test in the return value check should be replaced with NULL test. dpatch engine is used to auto generate this patch.
