Merge tag 'usb-3.7-rc3' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/usb 



Pull USB fixes from Greg Kroah-Hartman:
 "Here are a bunch of USB fixes for the 3.7-rc tree.

  There's a lot of small USB serial driver fixes, and one larger one
  (the mos7840 driver changes are mostly just moving code around to fix
  problems.) Thanks to Johan Hovold for finding the problems and fixing
  them all up.

  Other than those, there is the usual new device ids, xhci bugfixes,
  and gadget driver fixes, nothing out of the ordinary.
