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-bfin-twi.c:580:12: warning: 'i2c_bfin_twi_suspend' defined but not used [-Wunused-function] drivers/i2c/busses/i2c-bfin-twi.c:595:12: warning: 'i2c_bfin_twi_resume' defined but not used [-Wunused-function] Signed-off-by: Jingoo Han --- drivers/i2c/busses/i2c-bfin-twi.c | 2 ++ 1 files changed, 2 insertions(+), 0 deletions(-) diff --git a/drivers/i2c/busses/i2c-bfin-twi.c b/drivers/i2c/busses/i2c-bfin-twi.c index 05080c4..93663c0 100644 --- a/drivers/i2c/busses/i2c-bfin-twi.c +++ b/drivers/i2c/busses/i2c-bfin-twi.c @@ -575,6 +575,7 @@ static struct i2c_algorithm bfin_twi_algorithm = { .functionality = bfin_twi_functionality, }; +#ifdef CONFIG_PM_SLEEP static int i2c_bfin_twi_suspend(struct device *dev) { struct bfin_twi_iface *iface = dev_get_drvdata(dev); @@ -609,6 +610,7 @@ static int i2c_bfin_twi_resume(struct device *dev) return 0; } +#endif static SIMPLE_DEV_PM_OPS(i2c_bfin_twi_pm, i2c_bfin_twi_suspend, i2c_bfin_twi_resume); -- 1.7.2.5
