PCI: Move of_irq_parse_and_map_pci() declaration under OF_IRQ
Since commit 4670d610d592 ("PCI: Move OF-related PCI functions into PCI core"), sparc:allmodconfig fails to build with the following error. pcie-cadence-host.c:(.text+0x4c4): undefined reference to `of_irq_parse_and_map_pci' pcie-cadence-host.c:(.text+0x4c8): undefined reference to `of_irq_parse_and_map_pci' of_irq_parse_and_map_pci() is now only available if OF_IRQ is enabled. Make its declaration and its dummy function dependent on OF_IRQ to solve the problem. Fixes: 4670d610d592 ("PCI: Move OF-related PCI functions into PCI core") Signed-off-by: Guenter Roeck <linux@roeck-us.net> Signed-off-by: Bjorn Helgaas <bhelgaas@google.com> Acked-by: Rob Herring <robh@kernel.org>
