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.

Yes, as noted drivers/video/console/newport_con.c also uses fb_find_logo()
but the only other user of that in drivers/video/fbdev/core/fbmem.c.
