This function is only called from locations that return a -errno code, not just
-1.

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?
