From 7ec13187ef48b04bb7f6dfa266c7271a52d009c2 Mon Sep 17 00:00:00 2001 From: Ingo Molnar Date: Wed, 14 Oct 2009 15:06:42 +0200 Subject: [PATCH] x86, apic: Fix prototype in hw_irq.h MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit This warning: In file included from arch/x86/include/asm/ipi.h:23, from arch/x86/kernel/apic/apic_noop.c:27: arch/x86/include/asm/hw_irq.h:105: warning: ‘struct irq_desc’ declared inside parameter list arch/x86/include/asm/hw_irq.h:105: warning: its scope is only this definition or declaration, which is probably not what you want triggers because irq_desc is defined after hw_irq.h is included in irq.h. Since it's pointer reference only, a forward declaration of the type will solve the problem.
