From 1d6571a8794ba276a078a8ca9d84ccc157f8b6c3 Mon Sep 17 00:00:00 2001 From: Arnd Bergmann Date: Wed, 9 Aug 2023 12:07:56 +0200 Subject: arch: add missing prepare_ftrace_return() prototypes The prototype for prepare_ftrace_return() is architecture specific and can't be in a global header. Since it's normally called from assembly, it doesn't really need a prototype, but we get a warning if it's missing: arch/csky/kernel/ftrace.c:147:6: error: no previous prototype for 'prepare_ftrace_return' [-Werror=missing-prototypes] arch/microblaze/kernel/ftrace.c:22:6: error: no previous prototype for 'prepare_ftrace_return' [-Werror=missing-prototypes] arch/mips/kernel/ftrace.c:305:6: error: no previous prototype for 'prepare_ftrace_return' [-Werror=missing-prototypes] Add the prototypes for the three architectures that don't already have one in asm/ftrace.h.
