From b3e6916d6edfdf12505efbfb4a019e8a96f2c674 Mon Sep 17 00:00:00 2001 From: Wei Yongjun Date: Fri, 17 Jun 2016 17:34:17 +0000 Subject: [PATCH] staging: wilc1000: fix return value check in wlan_initialize_threads() 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().
