From d03516df837587368fc6e75591f6329c072b9eb5 Mon Sep 17 00:00:00 2001 From: Matthew Leach Date: Tue, 21 Jun 2016 16:19:49 +0100 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.
