[PATCH RFC 08/17] of: Do not use dev->iommu within of_iommu_configure()
This call chain is using dev->iommu->fwspec to pass around the fwspec between the three parts (of_iommu_configure(), of_iommu_xlate(), iommu_probe_device()). However there is no locking around the accesses to dev->iommu, so this is all racy. Allocate a clean, local, fwspec at the start of of_iomm
