Merge tag 'usb-4.11-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/usb

Pull USB/PHY updates from Greg KH:
 "Here is the big USB and PHY driver updates for 4.11-rc1.

  Nothing major, just the normal amount of churn in the usb gadget and
  dwc and xhci controllers, new device ids, new phy drivers, a new
  usb-serial driver, and a few other minor changes in different USB
  drivers.

  All have been in linux-next for a long time with no reported issues"
