*	[media] videobuf2-dma-sg: Replace vb2_dma_sg_desc with sg_table	Ricardo Ribalda	2013-09-26
\| \| \| \| \| \| \| \| \| \| \| \| \| \| \|	Replace the private struct vb2_dma_sg_desc with the struct sg_table so we can benefit from all the helping functions in lib/scatterlist.c for things like allocating the sg or compacting the descriptor. marvel-ccic and solo6x10 drivers, that use this API have been updated.
