    Subject[PATCH 12/20] PCI: qcom: update PCI config space remap function
    Date
    PCI configuration space should be mapped with a memory region type that
    generates on the CPU host bus non-posted write transations. Update the
    driver to use the devm_pci_remap_cfg* interface to make sure the correct
    memory mappings for PCI configuration space are used.
