[PATCH 1/7] drivers/net/wireless/b43/lo.c: remove unused variable

From: Julia Lawall
Date: Sat Mar 15 2008 - 12:03:27 EST


From: Julia Lawall <julia@xxxxxxx>

The variable trsw_rx is initialized but never used otherwise.

The semantic patch that makes this change is as follows:
(http://www.emn.fr/x-info/coccinelle/)

// <smpl>
@@
type T;
identifier i;
constant C;
@@

(
extern T i;
|
- T i;
<+... when != i
- i = C;
...+>
)
// </smpl>
