Date: Tue, 21 Jun 2016 16:19:49 +0100 From: Matthew Leach <matthew.leach@...ethink.co.uk> To: Greg Kroah-Hartman <gregkh@...uxfoundation.org>, Jiri Slaby <jslaby@...e.com> Cc: linux-serial@...r.kernel.org, linux-kernel@...r.kernel.org, linux-kernel@...ts.codethink.co.uk, Matthew Leach <matthew.leach@...ethink.co.uk> Subject: [PATCH] tty: serial: 8250: add CON_CONSDEV to flags 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.
