Subject: [net-next 01/10] net/mlx5e: Use IS_ERR() to check and simplify code
Date: Fri, 22 May 2020 16:51:39 -0700 [thread overview]
Message-ID: <20200522235148.28987-2-saeedm@mellanox.com> (raw)
In-Reply-To: <20200522235148.28987-1-saeedm@mellanox.com>
From: Tang Bin <tangbin@cmss.chinamobile.com>
Use IS_ERR() and PTR_ERR() instead of PTR_ERR_OR_ZERO() to
simplify code, avoid redundant judgements.
