ksz884x: delete useless variable
Delete a variable that is at most only assigned to a constant, but never
used otherwise. In this code, it is the variable result that is used for
the return code, not rc.
A simplified version of the semantic patch that fixes this problem is as
follows: (http://coccinelle.lip6.fr/)
// <smpl>
@@
type T;
identifier i;
constant c;
@@
-T i;
<... when != i
-i = c;
...>
// </smpl>
