Subject: [media] saa7164: fix return value check in saa7164_initdev() Author: Wei Yongjun <yongjun_...@trendmicro.com.cn> Date: Fri Oct 25 06:34:03 2013 -0300 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().
