    x86: devicetree: fix config option around x86_flattree_get_config() · 581e9290
    Frank Rowand authored
    x86_flattree_get_config() is incorrectly protected by
    ifdef CONFIG_OF_FLATTREE.  It uses of_get_flat_dt_size(), which
    only exists if CONFIG_OF_EARLY_FLATTREE.  This issue has not
    been exposed previously because OF_FLATTREE did not occur unless
    it was selected by OF_EARLY_FLATTREE.  A devicetree overlay change
    is selecting OF_FLATTREE directly instead of indirectly enabling
    it by selecting OF_EARLY_FLATTREE.
    
    This problem was exposed by a randconfig generated by the kbuild
    test robot, where Platform OLPC was enabled.  OLPC selects
    OF_PROMTREE instead of OF_EARLY_FLATREE.  The only other x86
    platform that selects OF is X86_INTEL_CE, which does select
    OF_EARLY_FLATTREE.
