The code I am suggesting is bascially yours without the retries
variable:
status = device_for_each_child(&ara->adapter->dev, &data,
smbus_do_alert);
if (data.addr == prev_addr && status != -EBUSY) {
device_for_each_child(&ara->adapter->dev, &data,
smbus_do_alert_force);
break;
}
prev_addr = data.addr;
Makes sense or am I missing something?
Yes, that should work and is indeed simpler. You are correct, the
additional loop should not be necessary since smbus_do_alert_force()
should already call all connected drivers and hopefully clear
the alert condition on those.
Great that we are aligned now! Do you have time to rework and test the
patch?
