From 2116bda6ad937d7acb6e2316fd9e65ad6ca01d42 Mon Sep 17 00:00:00 2001 From: Richard Weinberger Date: Mon, 11 Mar 2013 10:05:45 +0100 Subject: um: Use tty_port in SIGWINCH handler The tty below tty_port might get destroyed by the tty layer while we hold a reference to it. So we have to carry tty_port around...
