Merge tag 'usb-3.8-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/usb

Pull USB patches from Greg Kroah-Hartman:
 "Here's the big set of USB patches for 3.8-rc1.

  Lots of USB host driver cleanups in here, and a bit of a reorg of the
  EHCI driver to make it easier for the different EHCI platform drivers
  to all work together nicer, which was a reduction in overall code.  We
  also deleted some unused firmware files, and got rid of the very old
  file_storage usb gadget driver that had been broken for a long time.
  This means we ended up removing way more code than added, always a
  nice thing to see:
	 310 files changed, 3028 insertions(+), 10754 deletions(-)

  Other than that, the usual set of new device ids, driver fixes, gadget
  driver and controller updates and the like.

  All of these have been in the linux-next tree for a number of weeks.
