[PATCH net-next] net/mlx5: remove NULL check before dev_{put, hold}
From: zhang.songyi
Date: Wed Nov 30 2022 - 02:41:49 EST
From: zhang songyi <zhang.songyi@xxxxxxxxxx>
The call netdev_{put, hold} of dev_{put, hold} will check NULL,
so there is no need to check before using dev_{put, hold}.
Fix the following coccicheck warning:
/drivers/net/ethernet/mellanox/mlx5/core/lag/lag.c:1450:2-10:
WARNING:
WARNING NULL check before dev_{put, hold} functions is not needed.
