Subject: [PATCH -next] dmaengine: st_fdma: Fix the error return code in st_fdma_probe()
Date: Wed, 19 Oct 2016 13:23:50 +0000	[thread overview]
Message-ID: <1476883430-11970-1-git-send-email-weiyj.lk@gmail.com> (raw)

From: Wei Yongjun <weiyongjun1@huawei.com>

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