Make sure i2c_dw_pci_runtime_idle() is defined only when actually used, when CONFIG_PM_RUNTIME is defined. This fixes the following compilation warning: drivers/i2c/busses/i2c-designware-pcidrv.c:188:12: warning: ‘i2c_dw_pci_runtime_idle’ defined but not used [-Wunused-function] Signed-off-by: Vincent Stehlé <vincent.stehle@xxxxxxxxxxx> Cc: Wolfram Sang <wsa@xxxxxxxxxxxxx> --- drivers/i2c/busses/i2c-designware-pcidrv.c | 2 ++ 1 file changed, 2 insertions(+) diff --git a/drivers/i2c/busses/i2c-designware-pcidrv.c b/drivers/i2c/busses/i2c-designware-pcidrv.c index f6ed06c..2b5d3a6 100644 --- a/drivers/i2c/busses/i2c-designware-pcidrv.c +++ b/drivers/i2c/busses/i2c-designware-pcidrv.c @@ -185,6 +185,7 @@ static int i2c_dw_pci_resume(struct device *dev) return 0; } +#ifdef CONFIG_PM_RUNTIME static int i2c_dw_pci_runtime_idle(struct device *dev) { int err = pm_schedule_suspend(dev, 500); @@ -194,6 +195,7 @@ static int i2c_dw_pci_runtime_idle(struct device *dev) return 0; return -EBUSY; } +#endif static const struct dev_pm_ops i2c_dw_pm_ops = { .resume = i2c_dw_pci_resume, -- 1.8.4.rc3 -- To unsubscribe from this list: send the line "unsubscribe linux-i2c" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
