From d912156605b0eb3b3070dc7eabc43db6379aa43b Mon Sep 17 00:00:00 2001 From: Peter Hurley Date: Mon, 11 Mar 2013 16:44:33 -0400 Subject: tty: Don't reenable already enabled ldisc tty_ldisc_hangup() guarantees the ldisc is enabled (or that there is no ldisc). Since __tty_hangup() was the only user, re-define tty_ldisc_enable() in file-scope.
