There's no need to fail the probe here, you won't be able to read any DT properties but that shouldn't stop the driver binding.
If I'm not mistaken this is actually telling us to fail if the parent device (the PMIC itself) isn't present. I think I'll remove this as not necessary since if the parent node isn't present the mfd driver will never load, meaning this driver will never load either.
So it is - I edited incorrectly when I went to reply.
Below this line however we're failing if the codec node isn't present. Are you telling me we want to bind the driver if the node isn't present (such as in the edge case where the driver is present and the PMIC is a rk817, but the CODEC is not in use)? I will remove the return code if
Yes.
you think that is what needs to be done. My concern there though is if we do that we'll either be in a position to again report a bunch of errors for the edge case of users who want to use the PMIC but not the codec (in this case missing clocks and whatnot) if we try to bind the
Why would there be any errors?
