commit 7b9eaa7241ea2cfa580b854d461be72107a4b35c
CVE: CVE-2020-28915

It's prepare for fixing CVE-2020-28915.

--------------------------------

commit bb0890b4 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.
