Subject: PCI: rockchip: Update PCI config space remap function
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=995b76e48fe3cba4820ca42b4e0726cc5715a952;p=GitHub%2FLineageOS%2Fandroid_kernel_motorola_exynos9610.git

PCI: rockchip: 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.
