Subject: [PATCH] tty: serial: 8250: add CON_CONSDEV to flags
Date: Tue, 21 Jun 2016 16:19:49 +0100 [thread overview]
Message-ID: <1466522389-26943-1-git-send-email-matthew.leach@codethink.co.uk> (raw)
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.
