other places in drm, including i915 where this is coming from, use:
select FB_IOMEM_HELPERS if DRM_FBDEV_EMULATION
... and don't explicitly select FB_CORE. I think that is sufficient
following the chain of selects which ends up with DRM_CLIENT_LIB
selecting FB_CORE when DRM_FBDEV_EMULATION is set. Does that fixes it
for you?
