Robin Murphy c0d05cde2a iommu/of: Remove PCI host bridge node check ... of_pci_iommu_init() tries to be clever and stop its alias walk at the device represented by master_np, in case of weird PCI topologies where the bridge to the IOMMU and the rest of the system is not at the root. It turns out this is a bit short-sighted, since there are plenty of other callers of pci_for_each_dma_alias() which would also need the same behaviour in that situation, and the only platform so far with such a topology (Cavium ThunderX2) already solves it more generally via a PCI quirk. As this check is effectively redundant, and returning a boolean value as an int is a bit broken anyway, let's just get rid of it.
