2014-11-25[media] vb2-dma-sg: move dma_(un)map_sg hereHans Verkuil
This moves dma_(un)map_sg to the get_userptr/put_userptr and alloc/put memops of videobuf2-dma-sg.c and adds dma_sync_sg_for_device/cpu to the prepare/finish memops. Now that vb2-dma-sg will sync the buffers for you in the prepare/finish memops we can drop that from the drivers that use dma-sg. For the solo6x10 driver that was a bit more involved because it needs to copy JPEG or MPEG headers to the buffer before returning it to userspace, and that cannot be done in the old place since the buffer there is still setup for DMA access, not for CPU access. However, the buf_finish op is the ideal place to do this. By the time buf_finish is called the buffer is available for CPU access, so copying to the buffer is fine.
