Merge tag 'usb-3.19-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/usb

Pull USB updates from Greg KH:
 "Here's the big set of USB and PHY patches for 3.19-rc1.

  The normal churn in the USB gadget area is in here, as well as xhci
  and other individual USB driver updates.  The PHY tree is also in
  here, as there were dependancies on the USB tree.

  All of these have been in linux-next"
