Subject: media: saa7164: fix return value check in saa7164_initdev()
From: Wei Yongjun <yongjun_wei@xxxxxxxxxxxxxxxxx>
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().
