New Revision: 266006

  Change the USB audio kernel module linking order, so that the USB
  audio device driver is detached first and not its children. This fixes
  a panic in some cases when unloading "snd_uaudio" while a USB device
  is plugged. The linking order affects the order in which the module
  dependencies are registered.
