121  * Define device properties for a variable-length array _name.  A

123  * sets this property to the desired length of array, further dynamic
124  * properties "arrayname[0]", "arrayname[1]", ...  are defined so the

126  * "len-arrayname" property more than once is an error.
127  *
128  * When the array length is set, the @_field member of the device
129  * struct is set to the array length, and @_arrayfield is set to point
130  * to (zero-initialised) memory allocated for the array.  For a zero
131  * length array, @_field will be set to 0 and @_arrayfield to NULL.
132  * It is the responsibility of the device deinit code to free the
133  * @_arrayfield memory.
