Hi, I just updated from kernel 4.9 to 4.14 and found a NULL pointer
dereference caused by the iproc driver.
1) For bcma case pcie->dev->of_node can be NULL
2) iproc_pcie_map_dma_ranges calls pci_dma_range_parser_init
3) pci_dma_range_parser_init calls of_n_addr_cells(node) (node is NULL)
This is caused by a commit dd9d4e7498de3 ("PCI: iproc: Add inbound DMA
mapping support").
I believe that new DMA mapping code should be optional.
Would you find a moment to fix that, please?
