From mboxrd@z Thu Jan 1 00:00:00 1970 From: Matthew Leach Subject: [PATCH] tty: serial: 8250: add CON_CONSDEV to flags Date: Tue, 21 Jun 2016 16:19:49 +0100 Message-ID: <1466522389-26943-1-git-send-email-matthew.leach@codethink.co.uk> Return-path: Sender: linux-kernel-owner@vger.kernel.org To: Greg Kroah-Hartman , Jiri Slaby Cc: linux-serial@vger.kernel.org, linux-kernel@vger.kernel.org, linux-kernel@lists.codethink.co.uk, Matthew Leach List-Id: linux-serial@vger.kernel.org When using the 8250 as a boot console and the main console results in messages being printed twice. The console framework will only unregister boot consoles if a new console is registered with the CON_CONSDEV flag set. Set this flag for the univ8250 console to prevent double-registration.
