Subject: [PATCH v3 1/6] TTY: clean up port shutdown
Date: Thu, 7 Mar 2013 15:55:48 +0100 [thread overview]
Message-ID: <1362668153-10972-2-git-send-email-jhovold@gmail.com> (raw)
In-Reply-To: <1362668153-10972-1-git-send-email-jhovold-Re5JQEeQqe8AvxtiuMwx3w@public.gmane.org>
Untangle port-shutdown logic and make sure the initialised flag is
always cleared for non-console ports.
