Dear all: in usb_serial_probe, we create tty_port based on max_endpoints. My questions are: 1. some callback functions, such serial_hangup, serial_carrier_raised, etc. will called by tty layer with different tty_ports. how tty layer know these tty_ports? I only found tty_port_init to initial these tty_ports, but where we register these tty_ports to tty layer? -- Regards, -- To unsubscribe from this list: send the line "unsubscribe linux-usb" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
