Patch-mainline: v5.0-rc1
Git-commit: 61988bd281c9b08e0cc084f0b2da3b109c4c39c8
References: git-fixes

Drop LIST_HEAD where the variable it declares has never
been used.

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

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