Merge tag 'usb-4.8-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/usb

Pull more USB updates from Greg KH:
 "Here are a few more straggler patches for USB for 4.8-rc1.

  Most of these are for the usb-serial driver tree.  All of those have
  been in linux-next for a long time, but missed my previous pull
  request to you.

  The remaining change is to fix up a staging tree build error, due to
  some USB gadget driver changes that went in.  I put it in this tree as
  it was for a USB driver and people are reporting the build error on
  your tree.

  All of these have been in linux-next for this week, and longer for the
  usb-serial changes"
