comedi vmk80xx: Style improvements
Style improvements to comedi driver vmk80xx: * One variable definition per line * Block quotes start and end with near-empty lines * If..else statements use braces for both branches * Egregious blank lines removed * Use if..else rather than goto where trivial * Don't put function return type on a separate line Signed-off-by: J.
