Staging: go7007: Eliminate useless code
The variable s is initialized twice to the same (side effect-free)
expression. Drop one initialization.

(http://coccinelle.lip6.fr/)
// <smpl>
@forall@
idexpression *x;
identifier f!=ERR_PTR;
@@
x = f(...)
... when != x
(
x = f(...,<+...x...+>,...)
|
* x = f(...)
)
// </smpl>
