It's not like I'm a special Cavendish fan, but I think he didn't do much wrong there. It might not have been perfect, but come on, you cannot ask for a disqualificiation everytime a sprinter leaves his perfect straight line... it's road sprinting and of course you're trying to use the draft and of course you try to find the gaps, so you leave your line... the intermediate sprint was way dirtier in my opinion.
