No, you can have only up to NR_LDISCS ldiscs in the system and you have
to choose one of them to "handle" a particular tty.
IOW, you register an ldisc which is available for everybody then. And it
cannot have ->private_data since everybody would share this single
->private_data. Instead everybody comes with their devices as ttys which
have ->private_data for everybody's data and ->disc_data for you to note
anything about the (tty) device.
Am I missing something?
