From: Arvid Brodin <arvid.brodin@xxxxxxxx> This fixes a problem with my previous patch series where there's a great risk that the kernel will crash when unplugging interrupt devices from the USB port. These lines must have got missing when I rebased the patches from the older kernel I was working with to 2.6.37 and 2.6-next: This fixes a bug where the kernel may crash if you unplug a USB device that has active interrupt transfers.
