76
   HW_ADD_* will, if the property is not already present, add a
77
   property to the device.  Adding a property to a device after it has
78
   been created is a checked run-time error (use HW_SET_*).
79
 
80
   HW_SET_* will always update (or create) the property so that it has
81
   the specified value.  Changing the type of a property is a checked
82
   run-time error.
83
 
84
   FIND returns the specified properties value.  It is a checked
85
   runtime error to either request a nonexistant property or to
86
   request a property using the wrong type. Code locating a property
87
   should first check its type (using hw_find_property above) and then
88
   obtain its value using the below.
