From: Rob Herring <robh@kernel.org>

commit 7608158df3ed87a5c938c4a0b91f5b11101a9be1 upstream.

Commit e80a91ad302b ("PCI: Add dma_ranges window list") added a
dma_ranges resource list, but failed to correctly free the list when
devm_pci_alloc_host_bridge() is used.

Only the iproc host bridge driver is using the dma_ranges list.

Fixes: e80a91ad302b ("PCI: Add dma_ranges window list")
