Subject: [PATCH] hw/arm/smmu-common: a fix to smmu_find_smmu_pcibus
Date: Wed, 26 Feb 2020 18:26:28 +0100 [thread overview]
Message-ID: <20200226172628.17449-1-eric.auger@redhat.com> (raw)
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
