Subject: [PATCH 1/2] fpga: dfl: fme: fix return value check in in pr_mgmt_init()
Date: Thu, 16 Aug 2018 14:42:13 -0500 [thread overview]
Message-ID: <20180816194214.3462-2-atull@kernel.org> (raw)
In-Reply-To: <20180816194214.3462-1-atull@kernel.org>
From: Wei Yongjun <weiyongjun1@huawei.com>
In case of error, the function dfl_fme_create_region() returns ERR_PTR()
and never returns NULL. The NULL test in the return value check should
be replaced with IS_ERR().
Fixes: 29de76240e86 ("fpga: dfl: fme: add partial reconfiguration sub feature support")
