This isn't reporting an error code associated with the attempt to find a codec-sync GPIO, it's the result of some other operation.
What exactly is then the of_get_named_gpio() above please doing if not getting the codec sync GPIO? I am not following you, sorry.
It's not in any way involved in setting the value of ret, whatever value that has it's nothing to do with that operation.
