Merge tag 'usb-3.15-rc3' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/usb
Pull USB fixes from Greg KH:
"Here are a number of USB fixes for 3.15-rc3. The majority are gadget
fixes, as we didn't get any of those in for 3.15-rc2. The others are
all over the place, and there's a number of new device id addtions as
well."
