referencing other control values in the clustered control

Hi Hans,

I have a question about referencing control values.

For example:

1) "A" control and "B" control is clustered, and each is defined v4l2_ctrl a, b.
2) These two control is relevant, and start to make one process by real control "A".
3) The b->val is should be referenced for process in the "A" control function, even though in which is the "A".

And, in this case, 3) is right?
I mean, if the ctrl value clustered with another ctrl can be referenced in the another ctrl function, or not.
