This gives the following warning:

drivers/video/console/fbcon.c:407:20: warning: unused variable ‘ops’
[-Wunused-variable]

I can fix that. Or maybe it's better if you send a v2 with that fixed,
so that this gets properly to stable-kernel.

However, I wouldn't mind an acked-by or reviewed-by from someone.
