We currently have no integer menu controls, let alone one which would have a
set of standard values. We need same functionality as in
v4l2_ctrl_get_menu() for integer menus when we add the first standardised
integer menu control. I think it could be added at that time, or I could
implement a v4l2_ctrl_get_integer_menu() which would do nothing.
What do you think?
