 The 'new value' union is not used in g_volatile_ctrl. In general controls

 To mark a control as volatile you have to set the is_volatile flag:

 Obviously, all controls in the cluster array must be initialized to either
 a valid control or to NULL.
 
+In rare cases you might want to know which controls of a cluster actually
+were set explicitly by the user. For this you can check the 'is_new' flag of
+each control. For example, in the case of a volume/mute cluster the 'is_new'
+flag of the mute control would be set if the user called VIDIOC_S_CTRL for
+mute only. If the user would call VIDIOC_S_EXT_CTRLS for both mute and volume
+controls, then the 'is_new' flag would be 1 for both controls.
+
+The 'is_new' flag is always 1 when called from v4l2_ctrl_handler_setup().
