Subject: [PATCH -next] staging: android: ion: Fix return value check in hi6220_ion_probe()
Date: Thu, 15 Sep 2016 02:20:43 +0000	[thread overview]
Message-ID: <1473906043-28683-1-git-send-email-weiyj.lk@gmail.com> (raw)

From: Wei Yongjun <weiyongjun1@huawei.com>

In case of error, the function ion_device_create() returns ERR_PTR() and
never returns NULL. The NULL test in the return value check should be
replaced with IS_ERR().
