Commit 01306aeadd75 ("MIPS: prepare for user enabling of CONFIG_OF") changed the guards in asm/prom.h from CONFIG_OF to CONFIG_USE_OF, but missed the actual function declarations in kernel/prom.c, which have additional dependencies. Fixes the following build error: CC arch/mips/kernel/prom.o arch/mips/kernel/prom.c: In function '__dt_setup_arch': arch/mips/kernel/prom.c:54:2: error: implicit declaration of function 'early_init_dt_scan' [-Werror=implicit-function-declaration] if (!early_init_dt_scan(bph)) ^ Fixes: 01306aeadd75 ("MIPS: prepare for user enabling of CONFIG_OF") Signed-off-by: Jonas Gorski <jogo@xxxxxxxxxxx> --- arch/mips/kernel/prom.c | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) diff --git a/arch/mips/kernel/prom.c b/arch/mips/kernel/prom.c index b130033..5fcec30 100644 --- a/arch/mips/kernel/prom.c +++ b/arch/mips/kernel/prom.c @@ -38,7 +38,7 @@ char *mips_get_machine_name(void) return mips_machine_name; } -#ifdef CONFIG_OF +#ifdef CONFIG_USE_OF void __init early_init_dt_add_memory_arch(u64 base, u64 size) { return add_memory_region(base, size, BOOT_MEM_RAM); -- 2.1.4
