[PATCH] tty: serial: 8250: add CON_CONSDEV to flags

From: Matthew Leach
Date: Tue Jun 21 2016 - 11:24:39 EST


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.
