Subject: [PATCH] pci: imx: Adjust the return value when imx_pcie_addr_valid()
fails
When trying to access non-existent/unsupported PCI devices in
imx_pcie_read_config(), when imx_pcie_addr_valid() fails it returns
error code and fills in the result with 0xffffffff manually. But it
really should return zero to upper layer codes.
