USB: at91_udc: Cleanup variables after failure in usb_gadget_register_driver()

Browse source

This patch zeroes some variables when usb_gadget_register_driver()
fails. gadgetfs does a dummy registration to get the name of the USB
driver and then waits for user-land driver. If someone plugs the cable
in the meantime, bad things happen, because at91_udc has been left in
inconsistent state.
