…git/gregkh/usb

Pull USB patches from Greg Kroah-Hartman:
 "Here are a number of small USB patches for 3.6-rc3.

  The "large" one is just a number of device id updates to the option
  driver, done by the manufacturer, properly fixing up the device ids
  based on shipping devices.

  Other than that, some gadget driver fixes, the obligitary XHCI
  patches, and some other device ids and bugs fixed.

  Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>"
