[PATCH net-next] intel: Remove addressof casts to same type

[PATCH net-next] intel: Remove addressof casts to same type

[Joe Perches]

Using addressof then casting to the original type is pointless,
so remove these unnecessary casts.

Done via coccinelle script:

$ cat typecast.cocci 
@@
type T;
T foo;
@@

-	(T *)&foo
+	&foo
