[PATCH v2] iommu/arm-smmu-v3: Add a check to avoid invalid iotlb sync
by chenxiang 30 Mar '21

30 Mar '21

From: Xiang Chen <chenxiang66(a)hisilicon.com> It may send a invalid tlb sync for smmuv3 if iotlb_gather is not valid (iotlb_gather->pgsize = 0). So add a check to avoid invalid iotlb sync for it.
