Merge tag 'usb-3.6-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/usb

Pull USB patches from Greg Kroah-Hartman:
 "Here's the big USB patch set for the 3.6-rc1 merge window.

  Lots of little changes in here, primarily for gadget controllers and
  drivers.  There's some scsi changes that I think also went in through
  the scsi tree, but they merge just fine.  All of these patches have
  been in the linux-next tree for a while now.

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

Fix up trivial conflicts in include/scsi/scsi_device.h (same libata
conflict that Jeff had already encountered)
