Subject: [PATCH] net/mlx5: Use PTR_ERR_OR_ZERO rather than its implementation
Date:   Tue, 3 Sep 2019 14:56:10 +0800
Message-ID: <1567493770-20074-1-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 contains if(IS_ERR(...)) + PTR_ERR. It is better
to use it directly. hence just replace it.
