    helper: types: fix proper return type in example of ARRAY_SIZE()
    
    The example in the comment above the declaration of the macro
    ARRAY_SIZE() assigns the value to a variable of type 'unsigned'
    that is not allowed by the coding style (should be 'unsigned int')
    and is not correct since the macro uses 'sizeof()' and the type
    returned is 'size_t'.
    
    Fix the comment.
