Subject: PCI: qcom: Update PCI config space remap function
X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=10c736f784cb0dad0dce6ce938878a754676bc89;p=openwrt%2Fstaging%2Fblogic.git

PCI: qcom: Update PCI config space remap function

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.
