[PATCH 02/20] net/mlx5e: drop useless LIST_HEAD

From: Julia Lawall
Date: Sun Dec 23 2018 - 04:34:02 EST


Drop LIST_HEAD where the variable it declares is never used.

These became useless in 244cd96adb5f ("net_sched: remove list_head
from tc_action")

The semantic patch that fixes this problem is as follows:
(http://coccinelle.lip6.fr/)

// <smpl>
@@
identifier x;
@@
- LIST_HEAD(x);
... when != x
// </smpl>

Fixes: 244cd96adb5f ("net_sched: remove list_head from tc_action")
