This is because sleep PM callbacks defined by SIMPLE_DEV_PM_OPS are only used when the CONFIG_PM_SLEEP is enabled. warning: 'exynos5_i2c_suspend_noirq' defined but not used [-Wunused-function] warning: 'exynos5_i2c_resume_noirq' defined but not used [-Wunused-function] Signed-off-by: Jingoo Han --- drivers/i2c/busses/i2c-exynos5.c | 2 ++ 1 file changed, 2 insertions(+) diff --git a/drivers/i2c/busses/i2c-exynos5.c b/drivers/i2c/busses/i2c-exynos5.c index 9fd711c..60601ef 100644 --- a/drivers/i2c/busses/i2c-exynos5.c +++ b/drivers/i2c/busses/i2c-exynos5.c @@ -715,6 +715,7 @@ static int exynos5_i2c_remove(struct platform_device *pdev) return 0; } +#ifdef CONFIG_PM_SLEEP static int exynos5_i2c_suspend_noirq(struct device *dev) { struct platform_device *pdev = to_platform_device(dev); @@ -745,6 +746,7 @@ static int exynos5_i2c_resume_noirq(struct device *dev) return 0; } +#endif static SIMPLE_DEV_PM_OPS(exynos5_i2c_dev_pm_ops, exynos5_i2c_suspend_noirq, exynos5_i2c_resume_noirq); -- 1.7.10.4
