    Subject[PATCHv2 3/3] x86/mm: Fix enc_status_change_finish_noop()
    Date
    enc_status_change_finish_noop() defined as always-fail now which
    doesn't make sense for noop.

    The change doesn't have user-visible effect because it only gets
    called if the platform has CC_ATTR_MEM_ENCRYPT. All platforms with
    the attribute override the callback with own implementation.
