From fc362e2e0efd8b652ebfb409a4e43e6189c04f6f Mon Sep 17 00:00:00 2001 From: Hendrik Brueckner Date: Mon, 13 Oct 2008 23:12:48 +0000 Subject: hvc_console: Add a hangup notifier for backends I have added a hangup notifier that can be used by hvc console backends to handle a tty hangup. The default irq hangup notifier calls the notifier_del_irq() for compatibility.
