  78    HW_ADD_* will, if the property is not already present, add a
  79    property to the device.  Adding a property to a device after it has
  80    been created is a checked run-time error (use HW_SET_*).
  81
  82    HW_SET_* will always update (or create) the property so that it has
  83    the specified value.  Changing the type of a property is a checked
  84    run-time error.
  85
  86    FIND returns the specified properties value.  It is a checked
  87    runtime error to either request a nonexistant property or to
  88    request a property using the wrong type. Code locating a property
  89    should first check its type (using hw_find_property above) and then
  90    obtain its value using the below.
