From 734cc1783816ae358cef45673a29bf7af974e147 Mon Sep 17 00:00:00 2001 From: Jiri Slaby Date: Tue, 7 Aug 2012 21:47:47 +0200 Subject: TTY: use tty_port_register_device Currently we have no way to assign tty->port while performing tty installation. There are two ways to provide the link tty_struct => tty_port. Either by calling tty_port_install from tty->ops->install or tty_port_register_device called instead of tty_register_device when the device is being set up after connected. In this patch we modify most of the drivers to do the latter. When the drivers use tty_register_device and we have tty_port already, we switch to tty_port_register_device. So we have the tty_struct => tty_port link for free for those.
