* kraxel/tags/pull-usb-1:
  usb: move usb_{hi,lo} helpers to header file.
  usb: add vendor request defines
  trace-events: Clean up after removal of old usb-host code
  Revert "usb-tablet: Don't claim wakeup capability for USB-2 version"
  ehci: implement port wakeup
  xhci: Call usb_device_alloc/free_streams
  usb: Add usb_device_alloc/free_streams
  usb: Add max_streams attribute to endpoint info
  uas: s/ui/iu/
  uas: Fix response iu struct definition
  uas: Bounds check tags when using streams
  uas: Streams are numbered 1-y, rather then 0-x
  uas: Fix / cleanup usb_uas_task error handling
  uas: Only use report iu-s for task_mgmt status reporting
  scsi: Add 2 new sense codes needed by uas
  xhci: add support for suspend/resume
  xhci: Add a few missing checks for disconnected devices
