Add a cast so that this warning goes away: arch/mips/pci/pci.c: In function 'pcibios_init': arch/mips/pci/pci.c:165:45: warning: passing argument 2 of 'pci_fixup_irqs' from incompatible pointer type include/linux/pci.h:856:6: note: expected 'int (*)(struct pci_dev *, u8, u8)' but argument is of type 'struct pci_dev *' Signed-off-by: Kevin Cernekee --- Reference: http://www.mail-archive.com/gnewsense-dev@nongnu.org/msg00706.html It's been two years since the original discussion, and the warning is still there. It is now the only warning left in my kernel build. I was hoping we could get this resolved for good (one way or another). arch/mips/pci/pci.c | 3 ++- 1 files changed, 2 insertions(+), 1 deletions(-) diff --git a/arch/mips/pci/pci.c b/arch/mips/pci/pci.c index 33bba7b..9a35cd6 100644 --- a/arch/mips/pci/pci.c +++ b/arch/mips/pci/pci.c @@ -157,7 +157,8 @@ static int __init pcibios_init(void) for (hose = hose_head; hose; hose = hose->next) pcibios_scanbus(hose); - pci_fixup_irqs(pci_common_swizzle, pcibios_map_irq); + pci_fixup_irqs(pci_common_swizzle, + (int (*)(struct pci_dev *, u8, u8))pcibios_map_irq); pci_initialized = 1; -- 1.7.4.3 -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
