Subject: [net 01/12] net/mlx5e: Fix an error code in mlx5e_arfs_create_tables()
Date: Wed,  9 Jun 2021 17:21:44 -0700	[thread overview]
Message-ID: <20210610002155.196735-2-saeed@kernel.org> (raw)
In-Reply-To: <20210610002155.196735-1-saeed@kernel.org>

From: Yang Li <yang.lee@linux.alibaba.com>

When the code execute 'if (!priv->fs.arfs->wq)', the value of err is 0.
So, we use -ENOMEM to indicate that the function
create_singlethread_workqueue() return NULL.

Clean up smatch warning:
drivers/net/ethernet/mellanox/mlx5/core/en_arfs.c:373
mlx5e_arfs_create_tables() warn: missing error code 'err'.
