From e4408ce3c23f8451eff7a2954694598fb8fce833 Mon Sep 17 00:00:00 2001 From: Jiri Slaby Date: Thu, 7 Mar 2013 13:12:31 +0100 Subject: [PATCH] TTY: quatech2, remove unneeded is_open tty->ops->break_ctl cannot be called outside the gap between open and close. So there is no need to check whether the port is open in break_ctl in quatech2. Remove the check and also that member completely.
