58 Every TTY device shall be backed by a struct tty_port. Usually, TTY drivers
59 embed tty_port into device's private structures. Further details about handling
60 tty_port can be found in :doc:`tty_port`. The driver is also recommended to use
61 tty_port's reference counting by tty_port_get() and tty_port_put(). The final
62 put is supposed to free the tty_port including the device's private struct.
69 upon return, the device can be opened. There are also preferred tty_port
88 As stated earlier, every TTY device shall have a struct tty_port assigned to
