From 9642b78cdf3404ada759ccb7c7de461bf25597cb Mon Sep 17 00:00:00 2001 From: Bin Meng Date: Fri, 8 Jan 2016 01:03:20 -0800 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.
