Guennadi,

Your original patch were against the out-of-tree "media-specs/Makefile", present
only at the -hg tree. 

The way my conversion scripts work is that they'll convert the patches into a
patch that can be applied directly into -git. Among other things, all
changes on files outside the kernel tree are simply discarded by them.
 
Also, before patch 2/4, such addition won't be possible.

So, what happened here is that, after importing from your hg tree, I noticed 
-git compilation breakage. So, I ported the autobuild bits for media-entities & co,
manually added the missing pixfmt xml's and removed the duplicate symbol for one
of the bayer standards.

That's said, I don't really have any preference about the order where the files appear
at the Makefile. I have no objection if you prefer to add them on any other random order.

In a matter of fact, IMO, the better is to later write a patch that discards
this static list of files, auto-generating it dynamically.

So, if you really prefer a different order, please re-submit another version for this patch.

Cheers,
Mauro
