Subject: [PATCH 1/2] tools/power/x86/turbostat/turbostat.c: delete double assignment

From: Julia Lawall <Julia.Lawall@...6.fr>

Delete successive assignments to the same location.
Change the second assignment to the corresponding size variable, analogous
to the code below.

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

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

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