Subject: [PATCH 1/1] IB/ipoib: drop useless LIST_HEAD
Git-commit: 2fb458953a892020f36a323f386d8c7009f10777
Patch-mainline: v5.0
References: bsc#1111666
Drop LIST_HEAD where the variable it declares is never used.
Commit 31c02e215700 ("IPoIB: Avoid using stale last_send counter
when reaping AHs") removed the uses, but not the declaration.
The semantic patch that fixes this problem is as follows:
(http://coccinelle.lip6.fr/)
// <smpl>
@@
identifier x;
@@
- LIST_HEAD(x);
... when != x
// </smpl>
Fixes: 31c02e215700 ("IPoIB: Avoid using stale last_send counter when reaping AHs")
