    Subject[PATCH 5.4 165/168] powerpc/kuap: PPC_KUAP_DEBUG should depend on PPC_KUAP
    Date
    From: Michael Ellerman <mpe@ellerman.id.au>

    commit 61da50b76b62fd815aa82d853bf82bf4f69568f5 upstream.

    Currently you can enable PPC_KUAP_DEBUG when PPC_KUAP is disabled,
    even though the former has not effect without the latter.

    Fix it so that PPC_KUAP_DEBUG can only be enabled when PPC_KUAP is
    enabled, not when the platform could support KUAP (PPC_HAVE_KUAP).
