3.8.13.16 -stable review patch. If anyone has any objections, please let me know.

From: Wei Yongjun <yongjun_wei@trendmicro.com.cn>
commit 89f4d45b2752df5d222b5f63919ce59e2d8afaf4 upstream.
In case of error, the function kthread_run() returns ERR_PTR() and never returns NULL. The NULL test in the return value check should be replaced with IS_ERR().
