From 191c5f10275cfbb36802edadbdb10c73537327b4 Mon Sep 17 00:00:00 2001 From: Jiri Slaby Date: Thu, 15 Nov 2012 09:49:56 +0100 Subject: TTY: call tty_port_destroy in the rest of drivers 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. So fix the drivers to fulfil this assumption. To be sure, the TTY buffers (and later some stuff) are gone along with the tty_port, we have to call tty_port_destroy at tear-down places. This is mostly where the structure containing a tty_port is freed. This patch does exactly that -- put tty_port_destroy at those places.
