Subject: [PATCH] serial: samsung: only use earlycon for console
Date: Tue, 19 May 2015 22:26:04 +0200	[thread overview]
Message-ID: <3397068.2Doeo7zeZ1@wuerfel> (raw)

A configuration that enables earlycon but not the core console
code causes a link error:

  drivers/built-in.o: In function `setup_earlycon':
  drivers/tty/serial/earlycon.c:70: undefined reference to `uart_parse_earlycon'

That error can be triggered by the newly added samsung earlycon support,
which is missing a 'select' statement.

As suggested by Peter Hurley, solves the problem by moving the
'select SERIAL_EARLYCON' statement to the samsung console driver
option, as it is done by all other console drivers.
