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.
