From 736c9fd2902d919b075cf9cf371d1733c5ff635d Mon Sep 17 00:00:00 2001 From: Martin Schwidefsky Date: Tue, 8 Jan 2013 15:15:12 +0100 Subject: s390/3270: readd tty3270_open Reintroduce the tty3270_open function which has been removed by git commit 20cda6f2 "TTY: tty3270, add tty install". Without the open function in the tty_operations tty_open will return -ENODEV and the 3270 tty will not work.
