And here add something along the lines of: "Support for ``V4L2_CTRL_WHICH_MIN_VAL`` and ``V4L2_CTRL_WHICH_MAX_VAL`` is optional and depends on the ``V4L2_CTRL_FLAG_HAS_WHICH_MIN_MAX`` flag. See the documentation of the specific control on how to interpret the minimum and maximum values." This change should be made to patch 06/11 which introduces WHICH_MIN/MAX_VAL.
