Fair enough. I was looking for references to struct fb_info in the logo
code and found none. Sam's suggestion to move the remaining code from
fbdev to logo/ might be the way to go.

If we ever get that DRM boot-up client, it might want to use the logo as
well. Hence, it needs to be unrelated to fbdev.
