This function is only called from locations that return a -errno code, not just
> -1. > > Neil Hi Neil Looking up the references I see that some of the places looking at this return value from the probe function simply return their own -1 , and some return different enums relevant for their context. As they all look at !=0 or < 0 , but not all propagate the value they got I used an explicit -1. Do you have a specific enum in mind I should replace it with? /Arnon
