From 40704b129092eafce9c754199aea5a1f55c47fbc Mon Sep 17 00:00:00 2001 From: Arnd Bergmann Date: Fri, 18 Dec 2015 16:02:41 +0100 Subject: [PATCH] PCI: host: Add of_pci_get_host_bridge_resources() stub The pcie-rcar driver can be built for any ARM platform (for COMPILE_TEST) including those without CONFIG_OF enabled, and that results in a compile-time error: drivers/pci/host/pcie-rcar.c: In function 'rcar_pcie_parse_request_of_pci_ranges': drivers/pci/host/pcie-rcar.c:939:8: error: implicit declaration of function 'of_pci_get_host_bridge_resources' [-Werror=implicit-function-declaration] err = of_pci_get_host_bridge_resources(np, 0, 0xff, &pci->resources, &iobase); Add a of_pci_get_host_bridge_resources() stub function defined when CONFIG_OF_ADDRESS is disabled to allow compile-testing on all platforms. This mirrors what we do for other OF-specific functions.
