Subject: [PATCH] PCI: iproc: Fix NULL pointer dereference for BCMA
With the inbound DMA mapping supported added, the iProc PCIe driver
parses DT property "dma-ranges" through call to
"of_pci_dma_range_parser_init". In the case of BCMA, this results in a
NULL pointer deference due to a missing of_node.
Fix this by adding a guard in pcie-iproc-platform.c to only enable the
inbound DMA mapping logic when DT property "dma-ranges" is present
fixes: dd9d4e7498de3 ("PCI: iproc: Add inbound DMA mapping support")

FYI, if you want the patch to be applied please post it on linux-pci
in a separate thread.
Thanks,
Lorenzo
