I can improve the comment about the ADV7180: it is not clear why I'm 
removing that functions. (and the memory allocator commit is also in the 
todo list).

The STA2X11_VIP commit, I think is clear, I convert it to use videobu2 
and control framework. I can add some extra lines to explain why: 
because videobuf is obsolete

The actual code is the same of the previous one with yours (plural) 
suggestions from the RFC submission (few week ago). I did not write 
anything else.
