From c8bd2ac3b4c6c84c4a7cdceaed626247db698ab2 Mon Sep 17 00:00:00 2001 From: =?utf8?q?J=C3=A9r=C3=A9my=20Lefaure?= Date: Tue, 3 Jan 2017 18:13:49 -0600 Subject: [PATCH] usb: musb: fix compilation warning on unused function MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit The function musb_run_resume_work is called only when CONFIG_PM is enabled. So this function should not be defined when CONFIG_PM is disabled. Otherwise the compiler issues a warning: drivers/usb/musb/musb_core.c:2057:12: error: ‘musb_run_resume_work’ defined but not used [-Werror=unused-function] static int musb_run_resume_work(struct musb *musb) ^~~~~~~~~~~~~~~~~~~~ Signed-off-by: Jérémy Lefaure Signed-off-by: Bin Liu Signed-off-by: Greg Kroah-Hartman --- drivers/usb/musb/musb_core.c | 2 ++ 1 file changed, 2 insertions(+) diff --git a/drivers/usb/musb/musb_core.c b/drivers/usb/musb/musb_core.c index 9e226468a13e..fca288bbc800 100644 --- a/drivers/usb/musb/musb_core.c +++ b/drivers/usb/musb/musb_core.c @@ -2050,6 +2050,7 @@ struct musb_pending_work { struct list_head node; }; +#ifdef CONFIG_PM /* * Called from musb_runtime_resume(), musb_resume(), and * musb_queue_resume_work().
