From 057eb856eda1d957c0f1155eaa90739221f809a7 Mon Sep 17 00:00:00 2001 From: Jiri Slaby Date: Mon, 4 Jun 2012 13:35:37 +0200 Subject: TTY: add tty_port_register_device helper This will automatically assign tty_port to tty_driver's port array for later recall in tty_init_dev. This is intended to be called instead of tty_register_device.
