/**
 * struct tty_operations -- interface between driver and tty
 *
 * @lookup: ``struct tty_struct *()(struct tty_driver *self, struct file *,
 *				    int idx)``
 *
 *	Return the tty device corresponding to @idx, %NULL if there is not
 *	one currently in use and an %ERR_PTR value on error. Called under
 *	%tty_mutex (for now!)
 *
 *	Optional method. Default behaviour is to use the @self->ttys array.
 *
 * @install: ``int ()(struct tty_driver *self, struct tty_struct *tty)``
 *
 *	Install a new @tty into the @self's internal tables. Used in
 *	conjunction with @lookup and @remove methods.
 *
 *	Optional method. Default behaviour is to use the @self->ttys array.
 *
 * @remove: ``void ()(struct tty_driver *self, struct tty_struct *tty)``
 *
 *	Remove a closed @tty from the @self's internal tables. Used in
 *	conjunction with @lookup and @remove methods.
 *
 *	Optional method. Default behaviour is to use the @self->ttys array.
 *
 * @open: ``int ()(struct tty_struct *tty, struct file *)``
 *
 *	This routine is called when a particular @tty device is opened. This
 *	routine is mandatory; if this routine is not filled in, the attempted
 *	open will fail with %ENODEV.
 *
 *	Required method. Called with tty lock held. May sleep.
 *
 * @close: ``void ()(struct tty_struct *tty, struct file *)``
 *
 *	This routine is called when a particular @tty device is closed. At the
 *	point of return from this call the driver must make no further ldisc
 *	calls of any kind.
 *
 *	Remark: called even if the corresponding @open() failed.
 *
 *	Required method. Called with tty lock held. May sleep.
 *
 * @shutdown: ``void ()(struct tty_struct *tty)``
 *
 *	This routine is called
