Signed-off-by: Matti Vaittinen --- Depends on the mentioned return value change which is in patch 1/2. The return value change does also cause a functional change here. Eg. when IRQ mapping fails, the fwnode_irq_get_byname() no longer returns zero. This will cause also the probe here to return nonzero failure. I guess this is desired behaviour. --- drivers/i2c/i2c-smbus.c | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) diff --git a/drivers/i2c/i2c-smbus.c b/drivers/i2c/i2c-smbus.c index 07c92c8495a3..d0cc4b7903ed 100644 --- a/drivers/i2c/i2c-smbus.c +++ b/drivers/i2c/i2c-smbus.c @@ -130,7 +130,7 @@ static int smbalert_probe(struct i2c_client *ara, } else { irq = fwnode_irq_get_byname(dev_fwnode(adapter->dev.parent), "smbus_alert"); - if (irq <= 0) + if (irq < 0) return irq; }
