From cceba0e4b8f41a495dc7a5ab2795dcab0ddb64c1 Mon Sep 17 00:00:00 2001 From: Jingoo Han Date: Thu, 21 Mar 2013 19:09:01 -0700 Subject: leds: leds-bd2802: add CONFIG_PM_SLEEP to suspend/resume functions Add CONFIG_PM_SLEEP to suspend/resume functions to fix the following build warning when CONFIG_PM_SLEEP is not selected. This is because sleep PM callbacks defined by SIMPLE_DEV_PM_OPS are only used when the CONFIG_PM_SLEEP is enabled. drivers/leds/leds-bd2802.c:766:12: warning: 'bd2802_suspend' defined but not used [-Wunused-function] drivers/leds/leds-bd2802.c:776:12: warning: 'bd2802_resume' defined but not used [-Wunused-function] Signed-off-by: Jingoo Han Signed-off-by: Bryan Wu --- drivers/leds/leds-bd2802.c | 10 +++------- 1 file changed, 3 insertions(+), 7 deletions(-) (limited to 'drivers/leds/leds-bd2802.c') diff --git a/drivers/leds/leds-bd2802.c b/drivers/leds/leds-bd2802.c index 9f9177d29ed..2db04231a79 100644 --- a/drivers/leds/leds-bd2802.c +++ b/drivers/leds/leds-bd2802.c @@ -747,8 +747,7 @@ static int bd2802_remove(struct i2c_client *client) return 0; } -#ifdef CONFIG_PM - +#ifdef CONFIG_PM_SLEEP static void bd2802_restore_state(struct bd2802_led *led) { int i; @@ -785,12 +784,9 @@ static int bd2802_resume(struct device *dev) return 0; } +#endif static SIMPLE_DEV_PM_OPS(bd2802_pm, bd2802_suspend, bd2802_resume); -#define BD2802_PM (&bd2802_pm) -#else /* CONFIG_PM */ -#define BD2802_PM NULL -#endif static const struct i2c_device_id bd2802_id[] = { { "BD2802", 0 }, @@ -801,7 +797,7 @@ MODULE_DEVICE_TABLE(i2c, bd2802_id); static struct i2c_driver bd2802_i2c_driver = { .driver = { .name = "BD2802", - .pm = BD2802_PM, + .pm = &bd2802_pm, }, .probe = bd2802_probe, .remove = bd2802_remove, -- cgit v1.2.3
