From 668a920208fffaf5308aabd304f7568d6815169b Mon Sep 17 00:00:00 2001 From: Arnd Bergmann Date: Wed, 9 Aug 2023 23:10:49 +0200 Subject: [PATCH] m68k: Define __div64_32() to avoid a warning The generic __div64_32() definition is built on all architectures that don't provide this as a macro. m68k however neither defines nor requires __div64_32, so it should define an empty one to avoid the warning: lib/math/div64.c:31:32: error: no previous prototype for '__div64_32' [-Werror=missing-prototypes] Signed-off-by: Arnd Bergmann Reviewed-by: Geert Uytterhoeven Link: https://lore.kernel.org/r/20230809211057.60514-1-arnd@kernel.org Signed-off-by: Geert Uytterhoeven --- arch/m68k/include/asm/div64.h | 3 +++ 1 file changed, 3 insertions(+) diff --git a/arch/m68k/include/asm/div64.h b/arch/m68k/include/asm/div64.h index 365f39f5e256..df1f6b450cc5 100644 --- a/arch/m68k/include/asm/div64.h +++ b/arch/m68k/include/asm/div64.h @@ -31,6 +31,9 @@ __rem; \ }) +/* defining this stops the unused helper function from being built */ +#define __div64_32 __div64_32 + #endif /* CONFIG_CPU_HAS_NO_MULDIV64 */ #endif /* _M68K_DIV64_H */
