Are you referring to my previous patch by saying "then they get tweaked
to support a semi-dynamic state"? Those were just a proposal which was never
accepted and suggested to remove those tags all together.

Yes, I agree.  That's why in the first version I proposed the __usb_init,
__usb_exit, etc. tags which could be customized prior to including
composite related files.

I would still go with that solution but it was considered, let me
find the exact phrase, "Ick ick ick." :)

What's more, I don't see any other (that is cleaner) solution which
would allow flexibility so it seems what we can either choose
a non-flexible solution proposed by this patch or an ugly solution
proposed by my previous patch.

So basically, I trusted more experienced kernel developer's opinion
on this one.
