[PATCH 5/7] wusb: delete double assignment

From: Julia Lawall
Date: Sat Aug 23 2014 - 14:38:07 EST


From: Julia Lawall <Julia.Lawall@xxxxxxx>

Delete successive assignments to the same location.

A simplified version of the semantic match that finds this problem is as
follows: (http://coccinelle.lip6.fr/)

// <smpl>
@@
expression i;
@@

*i = ...;
i = ...;
// </smpl>
