Subject: [PATCH] x86/irq: Fix -Wmissing-prototypes warning for init_IRQ()
Date: Tue, 13 Nov 2018 09:56:29 +0800 [thread overview]
Message-ID: <1542074189-3208-1-git-send-email-wang.yi59@zte.com.cn> (raw)
We get a warning when building kernel with W=1:
arch/x86/kernel/irqinit.c:79:13: warning: no previous prototype for ‘init_IRQ’ [-Wmissing-prototypes]
void __init init_IRQ(void)
^
Add the missing declaration in head file to fix this.
