From 48a7466f4dd0104d87a6d8dd0f25027be89c8453 Mon Sep 17 00:00:00 2001 From: Jiri Slaby Date: Mon, 5 Mar 2012 14:52:55 +0100 Subject: TTY: isdn/gigaset, use tty_port Let us port the code to use tty_port. We now use open_count and tty from there. This allows us also to use tty_port_tty_set with tty refcounting instead of hand-written locking and logic. Note that tty and open_count are no longer protected by cs->lock. It is protected by tty_port->lock. But since all the places where they were used are now switched to the helpers, we are fine.
