  64  * @_arrayprop: PropertyInfo defining what property the array elements have
  65  * @_arraytype: C type of the array elements
  66  *
  67  * Define device properties for a variable-length array _name.  A
  68  * static property "len-arrayname" is defined. When the device creator
  69  * sets this property to the desired length of array, further dynamic
  70  * properties "arrayname[0]", "arrayname[1]", ...  are defined so the
  71  * device creator can set the array element values. Setting the
  72  * "len-arrayname" property more than once is an error.
  73  *
  74  * When the array length is set, the @_field member of the device
  75  * struct is set to the array length, and @_arrayfield is set to point
  76  * to (zero-initialised) memory allocated for the array.  For a zero
  77  * length array, @_field will be set to 0 and @_arrayfield to NULL.
  78  * It is the responsibility of the device deinit code to free the
  79  * @_arrayfield memory.
