From a321846492f9ce3bab27f826e6579217fbc35732 Mon Sep 17 00:00:00 2001 From: Peter Hurley Date: Tue, 27 Nov 2012 21:37:11 -0500 Subject: [PATCH] staging/fwserial: Destruct embedded tty_port on teardown For TTY drivers that manage the port lifetime, the tty_port should to be specifically destructed when the port lifetime ends. Now that a method has been added to do this, use it.
