    warning

[PATCH 1/2] MIPS: lantic: Fix pcibios_plat_dev_init() "no previous prototype" warning

[Bjorn Helgaas]

From: Bjorn Helgaas <bhelgaas@google.com>

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.

[PATCH 2/2] MIPS: lantic: Remove unnecessary include of <linux/of_irq.h>

[Bjorn Helgaas]

From: Bjorn Helgaas <bhelgaas@google.com>

arch/mips/pci/fixup-lantiq.c requires nothing from <linux/of_irq.h>, so
remove the include of it.

Indeed, we are good with <linux/of_pci.h>.

applied to mips-nextr. I've fixed lantic -> lantiq while applying.

Crap can work. Given enough thrust pigs will fly, but it's not necessarily a
good idea.                                                [ RFC1925, 2.3 ]
