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

32-rc series), and am relieved that it was "just" a silly driver bug.
