Merge tag 'usb-3.16-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/usb into next

Pull USB driver updates from Greg KH:
 "Here is the big USB driver pull request for 3.16-rc1.

  Nothing huge here, but lots of little things in the USB core, and in
  lots of drivers.  Hopefully the USB power management will be work
  better now that it has been reworked to do per-port power control
  dynamically.  There's also a raft of gadget driver updates and fixes,
  CONFIG_USB_DEBUG is finally gone now that everything has been
  converted over to the dynamic debug inteface, the last hold-out
  drivers were cleaned up and the config option removed.  There were
  also other minor things all through the drivers/usb/ tree, the
  shortlog shows this pretty well.

  All have been in linux-next, including the very last patch, which came
  from linux-next to fix a build issue on some platforms"
