Subject: [net-next V3 13/15] net/mlx5: Fix passing zero to 'PTR_ERR'
Date: Tue, 8 Dec 2020 11:35:53 -0800 [thread overview]
Message-ID: <20201208193555.674504-14-saeed@kernel.org> (raw)
In-Reply-To: <20201208193555.674504-1-saeed@kernel.org>
From: YueHaibing <yuehaibing@huawei•com>
Fix smatch warnings:
drivers/net/ethernet/mellanox/mlx5/core/esw/acl/egress_lgcy.c:105 esw_acl_egress_lgcy_setup() warn: passing zero to 'PTR_ERR'
drivers/net/ethernet/mellanox/mlx5/core/esw/acl/egress_ofld.c:177 esw_acl_egress_ofld_setup() warn: passing zero to 'PTR_ERR'
drivers/net/ethernet/mellanox/mlx5/core/esw/acl/ingress_lgcy.c:184 esw_acl_ingress_lgcy_setup() warn: passing zero to 'PTR_ERR'
drivers/net/ethernet/mellanox/mlx5/core/esw/acl/ingress_ofld.c:262 esw_acl_ingress_ofld_setup() warn: passing zero to 'PTR_ERR'
esw_acl_table_create() never returns NULL, so
NULL test should be removed.
