Commit 31db0dbd7244 ("net: hso: check for allocation failure in hso_create_bulk_serial_device()") recently started returning an error when the driver fails to allocate resources for the interrupt endpoint and tiocmget functionality. For consistency let's bail out from probe also if the URB allocation fails.
