From 6982a398426a22166eaf049b79544536fdd6429f Mon Sep 17 00:00:00 2001 From: Jiri Slaby Date: Thu, 7 Mar 2013 13:12:28 +0100 Subject: [PATCH] TTY: msm_smd_tty, clean up activate/shutdown Do not dig struct smd_tty_info out of tty_struct using tty_port_tty_get. It is unnecessarily too complicated, use simple container_of instead.
