Is this arch/ppc or arch/powerpc? I remember fixing this a while ago in

    ppc: Fix problem with recursive NDFC platform_device resource management

    This change fixes a problem with a resursive platform_device resource
    management of the AMCC 4xx NDFC. Without this fix a "cat /proc/iomem"
    leads to an infinite loop of printing the "ndfc-nand.0" resource.
