From dbe93977e523ff70ff66da824513d203207e394a Mon Sep 17 00:00:00 2001 From: Geert Uytterhoeven Date: Wed, 13 Sep 2023 16:07:58 +0200 Subject: [PATCH] m68k: kernel: Add and use "signal.h" MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit When building with W=1: arch/m68k/kernel/signal.c:756:18: warning: no previous prototype for ‘do_sigreturn’ [-Wmissing-prototypes] 756 | asmlinkage void *do_sigreturn(struct pt_regs *regs, struct switch_stack *sw) | ^~~~~~~~~~~~ arch/m68k/kernel/signal.c:783:18: warning: no previous prototype for ‘do_rt_sigreturn’ [-Wmissing-prototypes] 783 | asmlinkage void *do_rt_sigreturn(struct pt_regs *regs, struct switch_stack *sw) | ^~~~~~~~~~~~~~~ arch/m68k/kernel/signal.c:1112:17: warning: no previous prototype for ‘do_notify_resume’ [-Wmissing-prototypes] 1112 | asmlinkage void do_notify_resume(struct pt_regs *regs) | ^~~~~~~~~~~~~~~~ Fix this by introducing a new header file "signal.h" for holding the prototypes of functions implemented in arch/m68k/kernel/signal.c.
