[Bug 92870] GF117M nvkm_pmu_pgob fault

--- Comment #1 from Ilia Mirkin <imirkin-FrUbXkNCsVf2fBVCVOL8/A@public.gmane.org> ---
Interesting. The v4.3 kernel has:

void
nvkm_pmu_pgob(struct nvkm_pmu *pmu, bool enable)
{
        if (pmu->func->pgob)
                pmu->func->pgob(pmu, enable);
}

But Ben's latest upstream has:

void
nvkm_pmu_pgob(struct nvkm_pmu *pmu, bool enable)
{
        if (pmu && pmu->func->pgob)
                pmu->func->pgob(pmu, enable);
}

And indeed it looks like the GF117 is missing a PMU definition. I have no idea
why that'd be the case, but it was that way before the rewrite as well. The
simplest thing is to fix up that function as above, but I think we may also
want to enable the PMU on GF117.
