Subject: [PATCH] net/mlx5e: Fix an error code in mlx5e_arfs_create_tables()
Date: Wed, 2 Jun 2021 18:09:13 +0800 [thread overview]
Message-ID: <1622628553-89257-1-git-send-email-yang.lee@linux.alibaba.com> (raw)
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'.
Reported-by: Abaci Robot <abaci@linux.alibaba.com>
Fixes: 'commit f6755b80d693 ("net/mlx5e: Dynamic alloc arfs table for netdev when needed")'
