Ok, this is the usual backport issues we have every time we need to backport
patches upstream. This should be solved soon, but currently my priority is to
merge the pending patches at the tree. Up to then, you may do a:
	make menuconfig

and select only the drivers you need, or just revert the latest changepatch to
videobuf-dma-config.
