v4 fixes up an inversion of thr DR flag.

The preferred nomenclature is pnv_, not powernv_, but rng.c used
powernv_ for some reason, which isn't consistent with the rest. A recent

On POWER8 systems that don't have ibm,power-rng available, a guest that

We should avoid use the return value directly after call
iommu_pseries_alloc_group. Because it_may return a null.

Thanks, the fix resolves the issue for me.

We should call of_node_put() for the reference 'tsi' returned by
of_get_parent() which will increase the refcount.

Inserting of_node_put() in the 'if' condition is learned from Orsan:

for_each_node_by_type() will automatically increase and decrease
the refcount during the iteration. However, there is a reference
escaped into global 'fsl_pci_primary' and we need to handle it.

In pcibios_alloc_controller(), 'phb' is allocated and escaped into
global 'hose_list'. So we should call of_node_get() when a new reference
created into 'phb->dn'. And when phb is freed, we should call
of_node_put() on it.
