Subject[PATCH v3 10/13] software node: rename is_array to is_inline
Date
We do not need a special flag to know if we are dealing with an array, as we can
get that data from ration between element length and the data size, however we
do need a flag to know whether the data is stored directly inside property_entry
or separately.
