interrupts. If either of those later steps fails, the\nprobe function returns without unregistering the TCPCI port. The explicit\nunregister currently only happens from the remove callback.\n\nRegister a devres action immediately after tcpci_register_port() succeeds,\nso tcpci_unregister_port() runs on later probe failures and on driver\ndetach.
