From de274bfe0fc81def6ddb8a17020a9a4b56477cc4 Mon Sep 17 00:00:00 2001 From: Jiri Slaby Date: Thu, 15 Nov 2012 09:49:54 +0100 Subject: TTY: introduce tty_port_destroy After commit "TTY: move tty buffers to tty_port", the tty buffers are not freed in some drivers. This is because tty_port_destructor is not called whenever a tty_port is freed. This was an assumption I counted with but was unfortunately untrue. Those using refcounting are safe now, but for those which do not we introduce a function to be called right before the tty_port is freed by the drivers.
