From 6c395f66e98c895cf3ebf87c0b2fc63b6a57a196 Mon Sep 17 00:00:00 2001 From: Zhang Rui Date: Tue, 9 Jul 2019 21:19:12 +0800 Subject: [PATCH] drivers: thermal: processor_thermal_device: Fix build warning As a system sleep callback, proc_thermal_resume() should be defined only if CONFIG_PM_SLEEP is defined. This fixes a build warning when CONFIG_PM_SLEEP is not set, drivers/thermal/intel/int340x_thermal/processor_thermal_device.c:446:12: error: 'proc_thermal_resume' defined but not used [-Werror=unused-function] static int proc_thermal_resume(struct device *dev) Fixes: aaba9791fbb4 ("drivers: thermal: processor_thermal: Read PPCC on resume") Reported-by: Arnd Bergmann Signed-off-by: Zhang Rui --- .../thermal/intel/int340x_thermal/processor_thermal_device.c | 4 ++++ 1 file changed, 4 insertions(+) diff --git a/drivers/thermal/intel/int340x_thermal/processor_thermal_device.c b/drivers/thermal/intel/int340x_thermal/processor_thermal_device.c index a3210f09f366..77dae1e7c3bf 100644 --- a/drivers/thermal/intel/int340x_thermal/processor_thermal_device.c +++ b/drivers/thermal/intel/int340x_thermal/processor_thermal_device.c @@ -443,6 +443,7 @@ static void proc_thermal_pci_remove(struct pci_dev *pdev) pci_disable_device(pdev); } +#ifdef CONFIG_PM_SLEEP static int proc_thermal_resume(struct device *dev) { struct proc_thermal_device *proc_dev; @@ -452,6 +453,9 @@ static int proc_thermal_resume(struct device *dev) return 0; } +#else +#define proc_thermal_resume NULL +#endif static SIMPLE_DEV_PM_OPS(proc_thermal_pm, NULL, proc_thermal_resume);
