Yes. I meant to move drivers/video/logo/ to drivers/fbdev/core/logo and to
source its Kconfig from drivers/fbdev/core/Kconfig, since it now depends
on FB_CORE.

No, please rather leave it where it is. There's no code dependencies to 
the fbdev core; it merely depends on the Kconfig token.

Sure, fine by me. But I disagree that there's merely a Kconfig dependency.
The include/linux/linux_logo.h header declares both fb_find_logo() and
fb_append_extra_logo().

The fb_find_logo() function is defined in drivers/video/logo.c while the
fb_append_extra_logo() is in drivers/video/fbdev/core/fbmem.c, even though
only arch/powerpc/platforms/cell/spu_base.c uses fb_append_extra_logo().

So there's a relationship already between logo and fbdev/core, that's why
I wondered if would make sense to also move drivers/video/logo.c to have
both functions in there.

Or as I also suggested on irc - to pull out all the logo stuff from
fbmem and put it in video/logo/
With a bit of refactoring to make it obvious this is logo stuff and
maybe avoid some of the ifdeffery in the code of the users.
