Well, it could be defined I guess --- it shouldn't have any use if OF isn't
in use. I'll submit a patch for that.
The problem in the smiapp driver is better fixed by applying "smiapp: Use
of_property_read_u64_array() to read a 64-bit number array" instead. Could
you try that? I'll submit this as a fix then. of_read_number() was just a
workaround for missing of_property_read_u64_array().
