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 --- 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().
