From 0091cf5a6ae6e52fc95ceb53200975ef2c81c206 Mon Sep 17 00:00:00 2001 From: Kalle Pokki Date: Wed, 1 Nov 2006 15:08:13 +0200 Subject: [POWERPC] CPM_UART: Fix non-console initialisation The cpm_uart driver is initialised incorrectly, if there is a frame buffer console, and CONFIG_SERIAL_CPM_CONSOLE is defined. The driver fails to call cpm_uart_init_portdesc() and set_lineif() in this case.
