Subject: [PATCH 36/36] serial: apbuart: Fixup apbuart_console_init()

From: Thomas Gleixner <tglx@...utronix.de>

commit 35c64e5d (drivers: serial: apbuart: Handle OF failures
gracefully) missed that the modified grlib_apbuart_configure()
function is called from apbuart_console_init() as well.

Fix the fallout.
