Pull USB updates from Greg KH:
 "Here's the big USB pull request for 3.14-rc1

  Lots of little things all over the place, and the usual USB gadget
  updates, and XHCI fixes (some for an issue reported by a lot of
  people).  USB PHY updates as well as chipidea updates and fixes.

  All of these have been in the linux-next tree with no reported issues"

		This may allow the driver to support more hardware than

		was included in the driver's static device ID support

		table at compile time. The format for the device ID is:

		idVendor idProduct bInterfaceClass.

		idVendor idProduct bInterfaceClass RefIdVendor RefIdProduct

		The vendor ID and device ID fields are required, the

		interface class is optional.

		rest is optional. The Ref* tuple can be used to tell the

		driver to use the same driver_data for the new device as

		it is used for the reference device.

		Upon successfully adding an ID, the driver will probe

		for the device and attempt to bind to it.  For example:

		# echo "8086 10f5" > /sys/bus/usb/drivers/foo/new_id



		Here add a new device (0458:7045) using driver_data from

		an already supported device (0458:704c):

		# echo "0458 7045 0 0458 704c" > /sys/bus/usb/drivers/foo/new_id



		Reading from this file will list all dynamically added

		device IDs in the same format, with one entry per

		line. For example:
