From dfb03fb246dc893743a28d00966b1862ae836f2d Mon Sep 17 00:00:00 2001 From: Jingoo Han Date: Mon, 15 Jul 2013 11:28:59 +0900 Subject: [PATCH] i2c: designware: 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/i2c/busses/i2c-designware-platdrv.c:211:12: warning: 'dw_i2c_suspend' defined but not used [-Wunused-function] drivers/i2c/busses/i2c-designware-platdrv.c:221:12: warning: 'dw_i2c_resume' defined but not used [-Wunused-function] Signed-off-by: Jingoo Han Signed-off-by: Wolfram Sang --- drivers/i2c/busses/i2c-designware-platdrv.c | 9 ++++++--- 1 file changed, 6 insertions(+), 3 deletions(-) diff --git a/drivers/i2c/busses/i2c-designware-platdrv.c b/drivers/i2c/busses/i2c-designware-platdrv.c index 4c5fadabe49d..64ffb908641c 100644 --- a/drivers/i2c/busses/i2c-designware-platdrv.c +++ b/drivers/i2c/busses/i2c-designware-platdrv.c @@ -207,7 +207,7 @@ static const struct of_device_id dw_i2c_of_match[] = { MODULE_DEVICE_TABLE(of, dw_i2c_of_match); #endif -#ifdef CONFIG_PM +#ifdef CONFIG_PM_SLEEP static int dw_i2c_suspend(struct device *dev) { struct platform_device *pdev = to_platform_device(dev); @@ -228,9 +228,12 @@ static int dw_i2c_resume(struct device *dev) return 0; } -#endif static SIMPLE_DEV_PM_OPS(dw_i2c_dev_pm_ops, dw_i2c_suspend, dw_i2c_resume); +#define DW_I2C_DEV_PM_OPS (&dw_i2c_dev_pm_ops) +#else +#define DW_I2C_DEV_PM_OPS NULL +#endif /* work with hotplug and coldplug */ MODULE_ALIAS("platform:i2c_designware"); @@ -242,7 +245,7 @@ static struct platform_driver dw_i2c_driver = { .owner = THIS_MODULE, .of_match_table = of_match_ptr(dw_i2c_of_match), .acpi_match_table = ACPI_PTR(dw_i2c_acpi_match), - .pm = &dw_i2c_dev_pm_ops, + .pm = DW_I2C_DEV_PM_OPS, }, };
