The fwnode_irq_get_byname() was changed to not return 0 upon failure so return value check can be adjusted to reflect the change. Reviewed-by: Sakari Ailus <sakari.ailus@xxxxxxxxxxxxxxx> Reviewed-by: Andy Shevchenko <andriy.shevchenko@xxxxxxxxxxxxxxx> Signed-off-by: Matti Vaittinen <mazziesaccount@xxxxxxxxx> --- Revision history: v4 => v5: - Added back after this was accidentally dropped at v4. 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 - but I would appreciate any confirmation. Please, see also previous discussion here: https://lore.kernel.org/all/fbd52f5f5253b382b8d7b3e8046134de29f965b8.1666710197.git.mazziesaccount@xxxxxxxxx/ Another suggestion has been to drop the check altogether. I am slightly reluctant on doing that unless it gets confirmed that is the "right thing to do". --- 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 138c3f5e0093..893fe7cd3e41 100644 --- a/drivers/i2c/i2c-smbus.c +++ b/drivers/i2c/i2c-smbus.c @@ -129,7 +129,7 @@ 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; } -- 2.40.1 -- Matti Vaittinen, Linux device drivers ROHM Semiconductors, Finland SWDC Kiviharjunlenkki 1E 90220 OULU FINLAND ~~~ "I don't think so," said Rene Descartes.
