The pci-rcar driver is enabled for compile tests, and this has now shown that the driver cannot build without CONFIG_OF, following the inclusion of f8f2fe7355fb "PCI: rcar: Use new OF interrupt mapping when possible": ../drivers/pci/host/pcie-rcar.c: In function 'pci_dma_range_parser_init': ../drivers/pci/host/pcie-rcar.c:856:2: error: implicit declaration of function 'of_n_addr_cells' [-Werror=implicit-function-declaration] parser->pna = of_n_addr_cells(node); ^ As pointed out by Ben Dooks and Geert Uytterhoeven, this is actually supposed to build fine, which we can achieve if we make the declaration of of_irq_parse_and_map_pci conditional on CONFIG_OF and provide an empty inline function otherwise, as we do for a lot of other of interfaces. This lets us build the rcar_pci driver again without CONFIG_OF for build testing. All platforms using this driver select OF, so this doesn't change anything for the users.
