From 59fa5860204ffc95128d60cba9f54f9740a42c7d Mon Sep 17 00:00:00 2001 From: Matt Redfearn Date: Tue, 24 May 2016 11:42:30 +0100 Subject: [PATCH] genirq: Fix missing return value in irq_destroy_ipi() MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Commit 7cec18a3906b changed the return type of irq_destroy_ipi to int, but missed adding a value to one return statement. Fix this to silence the resulting compiler warning: kernel/irq/ipi.c In function ‘irq_destroy_ipi’: kernel/irq/ipi.c:128:3: warning: ‘return’ with no value, in function returning non-void [-Wreturn-type] Fixes: 7cec18a3906b "genirq: Add error code reporting to irq_{reserve,destroy}_ipi" Signed-off-by: Matt Redfearn Cc: linux-mips@linux-mips.org Link: http://lkml.kernel.org/r/1464086550-24734-1-git-send-email-matt.redfearn@imgtec.com Signed-off-by: Thomas Gleixner --- kernel/irq/ipi.c | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) diff --git a/kernel/irq/ipi.c b/kernel/irq/ipi.c index c42742208e5e..89b49f6773f0 100644 --- a/kernel/irq/ipi.c +++ b/kernel/irq/ipi.c @@ -125,7 +125,7 @@ int irq_destroy_ipi(unsigned int irq, const struct cpumask *dest) domain = data->domain; if (WARN_ON(domain == NULL)) - return; + return -EINVAL; if (!irq_domain_is_ipi(domain)) { pr_warn("Trying to destroy a non IPI domain!\n");
