u2fzero_fill_in_urb() allocates dev->urb with usb_alloc_urb(), but u2fzero_probe() ignored its return value and only freed the URB from u2fzero_remove(). If LED or hwrng registration fails after the URB allocation, probe returns an error and the driver core does not call .remove(), leaking the URB. A failed URB setup was also allowed to continue probing with an unusable device. Check the URB setup result and add the missing probe-error unwind so the URB is freed before returning from later errors.
