   4 Subject: [PATCH] pcie-brcmstb: Don't set DMA ops for root complex
   5
   6 A change to arm_get_dma_map_ops has stopped get_dma_ops from working
   7 on the root complex, causing an error to be logged. However, there is
   8 no need to override the DMA ops in that case, so skip it and
   9 eliminate the error message.
