Subject: [PATCH] staging:pci-mt7621: Use PTR_ERR_OR_ZERO to replace the open code
Date:   Mon, 13 Aug 2018 18:54:59 +0800
Message-ID: <1534157699-23637-1-git-send-email-zhongjiang@huawei.com>
MIME-Version: 1.0
Content-Type: text/plain
Sender: linux-kernel-owner@vger.kernel.org
Precedence: bulk

PTR_ERR_OR_ZERO has implemented the if(IS_ERR(...)) + PTR_ERR, So
just replace them rather than duplicating its implement.
