A number of drivers in mainline relies on this function working for sparc. The bug was introduced in a850a7554442f08d3e910c6eeb4ee216868dda1e, "of/address: add empty static inlines for !CONFIG_OF". Contrary to that commit title, the static inlines are added for !CONFIG_OF_ADRESS, and CONFIG_OF_ADRESS is never defined for sparc. This is good behavior for the other functions in include/linux/of_address.h, as the extern functions defined in drivers/of/address.c only gets linked when OF_ADDRESS is configured. However, for of_address_to_resource is that there exists a sparc-specific implementation in arch/sparc/arch/sparc/kernel/of_device_common.c Signed-off-by: Andreas Larsson --- arch/sparc/include/asm/prom.h | 5 +++++ include/linux/of_address.h | 2 ++ 2 files changed, 7 insertions(+), 0 deletions(-) diff --git a/arch/sparc/include/asm/prom.h b/arch/sparc/include/asm/prom.h index c287651..f930031 100644 --- a/arch/sparc/include/asm/prom.h +++ b/arch/sparc/include/asm/prom.h @@ -63,5 +63,10 @@ extern char *of_console_options; extern void irq_trans_init(struct device_node *dp); extern char *build_path_component(struct device_node *dp); +/* SPARC has a local implementation */ +extern int of_address_to_resource(struct device_node *dev, int index, + struct resource *r); +#define of_address_to_resource of_address_to_resource + #endif /* __KERNEL__ */ #endif /* _SPARC_PROM_H */ diff --git a/include/linux/of_address.h b/include/linux/of_address.h index a1984dd..e20e3af 100644 --- a/include/linux/of_address.h +++ b/include/linux/of_address.h @@ -28,11 +28,13 @@ static inline unsigned long pci_address_to_pio(phys_addr_t addr) { return -1; } #endif #else /* CONFIG_OF_ADDRESS */ +#ifndef of_address_to_resource static inline int of_address_to_resource(struct device_node *dev, int index, struct resource *r) { return -EINVAL; } +#endif static inline struct device_node *of_find_matching_node_by_address( struct device_node *from, const struct of_device_id *matches, -- 1.7.0.4
