The function dma_get_sgtable will allocate a sg table internally so
it is not necessary to allocate a sg table before it. The unnecessary
'sg_alloc_table' call is removed.

It's good catch. Right, I missed it. dma_get_sgtable function also calls sg_alloc_table.
ret = dma_get_sgtable(drm_dev->dev, sgt, buf->kvaddr,
