Subject: PCI: xilinx: Fix harmless format string warning
From: Arnd Bergmann <arnd@xxxxxxxx>
commit abc596b9a2f3d24b8b0d637bdb071aae7f09801d upstream.
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.
Fixes: 00b4d9a1412 ("bitops: Fix shift overflow in GENMASK macros")
