-Subject: [PATCH] PCI: iproc: Fix NULL pointer dereference for BCMA
-MIME-Version: 1.0
-Content-Type: text/plain; charset=UTF-8
-Content-Transfer-Encoding: 8bit
-
-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")
