Ok. I committed the one-liner patch to fix the oops (confirmed by Rafael), 
but I'm leaving the memory leak for you as I'm not going to commit some 
untested patch at this stage.

Thanks to everybody involved, I was personally very nervous that this was 
something much more fundamental (we've had some scary bugs during the 
32-rc series), and am relieved that it was "just" a silly driver bug.
