From 79f999d0aa264f72f5491be14b4bf60137a3d3a9 Mon Sep 17 00:00:00 2001 From: Alan Cox Date: Mon, 12 May 2008 12:29:25 +0100 Subject: strip: Fix termios assumption Strip assumes that the tty drivers always have a set_termios method which may not be true. Check this when binding to the tty so that we don't oops later.
