Subject: [PATCH v3 3/5] serial: 8250/uniphier: fix modular build
Date: Wed, 17 Feb 2016 16:02:33 +0100 [thread overview]
Message-ID: <1455721357-4008289-4-git-send-email-arnd@arndb.de> (raw)
In-Reply-To: <1455721357-4008289-1-git-send-email-arnd@arndb.de>
The newly added uniphier serial port driver fails to build as
a loadable module when the base 8250 driver is built-in and
its console support enabled:
ERROR: "early_serial8250_setup" [drivers/tty/serial/8250/8250_uniphier.ko] undefined!
This changes the driver to only provide the early console support
if it is built-in itself as well.
