Without CONFIG_DMA_SHARED_BUFFER we run into a link error for the
dma_buf_* APIs:
ERROR: "dma_buf_map_attachment" [drivers/staging/media/tegra-vde/tegra-vde.ko] undefined!
ERROR: "dma_buf_attach" [drivers/staging/media/tegra-vde/tegra-vde.ko] undefined!
ERROR: "dma_buf_get" [drivers/staging/media/tegra-vde/tegra-vde.ko] undefined!
ERROR: "dma_buf_put" [drivers/staging/media/tegra-vde/tegra-vde.ko] undefined!
ERROR: "dma_buf_detach" [drivers/staging/media/tegra-vde/tegra-vde.ko] undefined!
ERROR: "dma_buf_unmap_attachment" [drivers/staging/media/tegra-vde/tegra-vde.ko] undefined!
