It's not really Linux kernel style, it's just my style...  I wouldn't
have complained if the original code were consistent one way or the
other.  But since I was encouraging you to pick a style and use it
consistently, then I'm always going to advocate my style...  :P

Anyway, thanks!  Looks good to me.
