Applied to net-next-mlx5, Thanks. > goto out; > + } > + > fallthrough; > case MLX5_CAP_INLINE_MODE_L2: > NL_SET_ERR_MSG_MOD(extack, "Inline mode can't be > set");

The return value is missing in this code scenario, add the return value '0' to the return value 'err'. Eliminate the follow smatch warning: drivers/net/ethernet/mellanox/mlx5/core/eswitch_offloads.c:3083 mlx5_devlink_eswitch_inline_mode_set() warn: missing error code 'err'.
