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.

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:
