Subject: IB/ipoib: drop useless LIST_HEAD
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=2fb458953a892020f36a323f386d8c7009f10777;p=people%2Fms%2Flinux.git

IB/ipoib: drop useless LIST_HEAD

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")
