Yeah, that was my intention, I'll fold it there to keep bisection, thanks for fixing it so fast, I'll double check on my rk3399 board and on again on the cross-build container. - Arnaldo > > Thanks, > Ian > > > Signed-off-by: Ian Rogers <irogers@google.com> > > --- > > tools/perf/arch/arm64/util/pmu.c | 2 ++ > > 1 file changed, 2 insertions(+) > > > > diff --git a/tools/perf/arch/arm64/util/pmu.c b/tools/perf/arch/arm64/util/pmu.c > > index 2779840d8896..fa143acb4c8d 100644 > > --- a/tools/perf/arch/arm64/util/pmu.c > > +++ b/tools/perf/arch/arm64/util/pmu.c > > @@ -22,6 +22,8 @@ static struct perf_pmu *pmu__find_core_pmu(void) > > return NULL; > > > > return pmu; > > + } > > + return NULL; > > } > > > > const struct pmu_metrics_table *pmu_metrics_table__find(void) > > -- > > 2.39.1.519.gcb327c4b5f-goog > >
