From: Peilin Ye <yepeilin...@gmail.com> commit bb0890b4cd7f8203e3aa99c6d0f062d6acdaad27 upstream.
drivers/video/console/newport_con.c is borrowing FONT_EXTRA_WORDS macros from drivers/video/fbdev/core/fbcon.h. To keep things simple, move all definitions into <linux/font.h>. Since newport_con now uses four extra words, initialize the fourth word in newport_set_font() properly.
