Merge tag 'usb-4.7-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/usb

Pull USB updates from Greg KH:
 "Here's the big pull request for USB and PHY drivers for 4.7-rc1

  Full details in the shortlog, but it's the normal major gadget driver
  updates, phy updates, new usbip code, as well as a bit of lots of
  other stuff.

  All have been in linux-next with no reported issues"
