From abc596b9a2f3d24b8b0d637bdb071aae7f09801d Mon Sep 17 00:00:00 2001 From: Arnd Bergmann Date: Tue, 13 Jan 2015 15:20:05 +0100 Subject: PCI: xilinx: Fix harmless format string warning The xilinx PCIe driver prints a register value whose type is propagated to the type returned by the GENMASK() macro. Unfortunately, that type has recently changed as the result of a bug fix, so now we get a warning about the type: drivers/pci/host/pcie-xilinx.c: In function 'xilinx_pcie_clear_err_interrupts': drivers/pci/host/pcie-xilinx.c:154:3: warning: format '%d' expects argument of type 'int', but argument 4 has type 'long unsigned int' [-Wformat=] Change the code so we always print the number as an 'unsigned long' type to avoid the warning. The original code was fine on 32-bit architectures but not on 64-bit. Now it works as expected on both.
