From: Bjorn Helgaas <bhelgaas@xxxxxxxxxx> After bbd8810d3998 ("PCI: Remove unused includes and superfluous struct declaration"), <linux/of_pci.h> no longer includes <linux/pci.h>, which provides the extern declarations for pcibios_plat_dev_init() and pcibios_map_irq() via <asm/pci.h>. This results in these new warnings: arch/mips/pci/fixup-lantiq.c:13:5: warning: no previous prototype for 'pcibios_plat_dev_init' [-Wmissing-prototypes] arch/mips/pci/fixup-lantiq.c:24:5: warning: no previous prototype for 'pcibios_map_irq' [-Wmissing-prototypes] Include <linux/pci.h> directly to get these declarations.
