Merge tag 'usb-4.12-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/usb

Pull USB updates from Greg KH:
 "Here is the big USB patchset for 4.12-rc1.

  Lots of good stuff here, after many many many attempts, the kernel
  finally has a working typeC interface, many thanks to Heikki and
  Guenter and others who have taken the time to get this merged. It
  wasn't an easy path for them at all.

  There's also a staging driver that uses this new api, which is why
  it's coming in through this tree.

  Along with that, there's the usual huge number of changes for gadget
  drivers, xhci, and other stuff. Johan also finally refactored pretty
  much every driver that was looking at USB endpoints to do it in a
  common way, which will help prevent any "badly-formed" devices from
  causing problems in drivers. That too wasn't a simple task.

  All of these have been in linux-next for a while with no reported
  issues"
