Subject: [net-next 11/16] net/mlx5: Simplify mlx5_register_device to return void
Date: Wed, 25 Mar 2020 23:38:04 -0700	[thread overview]
Message-ID: <20200326063809.139919-12-saeedm@mellanox.com> (raw)
In-Reply-To: <20200326063809.139919-1-saeedm@mellanox.com>

From: Parav Pandit <parav@mellanox.com>

mlx5_register_device() doesn't check for any error and always returns 0.
Simplify mlx5_register_device() to return void and its caller, remove
dead code related to it.
