usb: xhci: Clean up error code in xhci_dbc_tty_register_device() tty_port_register_device() returns error pointers on error, never NULL. The IS_ERR_OR_NULL() function returns either 1 or 0 so it means we return 1 on error instead of a proper error code. The caller only checks for zero vs non-zero so this doesn't affect runtime.
