From aa27a094e2c2e0cc59914e56113b860f524f4479 Mon Sep 17 00:00:00 2001 From: Jiri Slaby Date: Thu, 7 Mar 2013 13:12:30 +0100 Subject: TTY: add tty_port_tty_hangup helper It allows for cleaning up on a considerable amount of places. They did port_get, hangup, kref_put. Now the only thing needed is to call tty_port_tty_hangup which does exactly that. And they can also decide whether to consider CLOCAL or completely ignore that.
