Merge tag 'usb-3.15-rc8' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/usb 

Pull USB fixes from Greg KH:
 "Here are some fixes for 3.15-rc8 that resolve a number of tiny USB
  issues that have been reported, and there are some new device ids as
  well.

  All have been tested in linux-next"

* tag 'usb-3.15-rc8' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/usb:
  xhci: delete endpoints from bandwidth list before freeing whole device
  usb: pci-quirks: Prevent Sony VAIO t-series from switching usb ports
  USB: cdc-wdm: properly include types.h
  usb: cdc-wdm: export cdc-wdm uapi header
  USB: serial: option: add support for Novatel E371 PCIe card
  USB: ftdi_sio: add NovaTech OrionLXm product ID
  USB: io_ti: fix firmware download on big-endian machines (part 2)
