2.6.31-stable review patch. If anyone has any objections, please let us know. ------------------ From: Sarah Sharp commit 9191eee7b8a0e18c07c06d6da502706805cab6d2 upstream. On a successful transfer, urb->td is freed before the URB is ready to be given back to the driver. Don't touch urb->td after it's freed. This bug would have only shown up when xHCI debugging was turned on, and the freed memory was quickly reused for something else.
