This would require maintainance. Yes, it is easy to do, but the problem 
is that it is just one extra thing to remember. One extra task. One more 
rule to try to enforce. One more thing that some guy will forget. One 
more extra patch that will have to be sent in at the last minute.

Instead, please use the wiki:

I propose a compromise, please try it out and tell me what you think:

This patch creates a boolean dependency link for VIDEO_CX88_VP3054, so 
that it's tristate value will be the same as that of VIDEO_CX88_DVB

The reason for this patch is to fix up the indentation order within the 
individual frontend selection menus for cx88-dvb.

The patch is correct, although the explanation is a bit difficult. ;-)
