Koen Vandeputte 432dd7064a ARM: cns3xxx: Use actual size reads for PCIe ... commit 802b7c06ad ("ARM: cns3xxx: Convert PCI to use generic config accessors") reimplemented cns3xxx_pci_read_config() using pci_generic_config_read32(), which preserved the property of only doing 32-bit reads. It also replaced cns3xxx_pci_write_config() with pci_generic_config_write(), so it changed writes from always being 32 bits to being the actual size, which works just fine. Given that: - The documentation does not mention that only 32 bit access is allowed. - Writes are already executed using the actual size - Extensive testing shows that 8b, 16b and 32b reads work as intended Allow read access of any size by replacing pci_generic_config_read32() with the pci_generic_config_read() accessors.
