Is that true? As far as I can see, since commit bd69f73f2c81
("of: Create function for counting number of phandles in a property")
it returns the (positive) number of entries if index is negative and the
'resets' property exists and parses correctly (before it would return
-ENOENT). If there are parsing errors, it can also return -EINVAL.
