From: Julia Lawall <julia@diku.dk>

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>
