Mixing code and declarations is C99 and I'm afraid kernel developers 
haven't gotten around to upgrading themselves for the last 9 years yet 
so this is unfortunately not accepted style.

I'm afraid you need a { } code block so that the declaration can go at 
the top of that to stay C89 compatible.
