hw/arm/smmu-common: a fix to smmu_find_smmu_pcibus
Make sure a null SMMUPciBus is returned in case we were not able to identify a pci bus matching the @bus_num. This matches the fix done on intel iommu in commit: a2e1cd41ccfe796529abfd1b6aeb1dd4393762a2 Signed-off-by: Eric Auger <eric.auger@redhat.com> Reviewed-by: Peter Xu <peterx@redhat.com> Message-Id: <20200226172628.17449-1-eric.auger@redhat.com> Reviewed-by: Philippe Mathieu-Daudé <philmd@redhat.com> Signed-off-by: Philippe Mathieu-Daudé <philmd@redhat.com> Signed-off-by: Peter Maydell <peter.maydell@linaro.org>
