  videobuf_queue_dma_contig_init_cached() is not used anywhere.
  Drop support for it, cleaning up the code a little bit.

• 08bff03ed   V4L/DVB: videobuf: add ext_lock argument to the queue init functions ... Browse Code »

  Add an ext_lock argument to the videobuf init functions. This allows
  drivers to pass the vdev->lock pointer (or any other externally held lock)
  to videobuf. For now all drivers just pass NULL.

  The videobuf_queue_ops function vector is not declared constant, but
  there's no need for the videobuf layer to ever change it. Make it const
  so that videobuf users can make their operations const without warnings.

• 2cc45cf25   V4L/DVB (8341): videobuf: Add physically contiguous queue code V3 ... Browse Code »

  This is V3 of the physically contiguous videobuf queues patch.
  Useful for hardware such as the SuperH Mobile CEU which doesn't
  support scatter gatter bus mastering.

  Since it may be difficult to allocate large chunks of physically
  contiguous memory after some uptime due to fragmentation, this code
  allocates memory using dma_alloc_coherent(). Architectures supporting
  dma_declare_coherent_memory() can easily avoid fragmentation issues
  by using dma_declare_coherent_memory() to force dma_alloc_coherent()
  to allocate from a certain pre-allocated memory area.

  Changes since V2
  - use dma_handle for physical address
  - use "scatter gather" instead of "scatter gatter"

  Changes since V1:
  - use dev_err() instead of pr_err()
  - remember size in struct videobuf_dma_contig_memory
  - keep struct videobuf_dma_contig_memory in .c file
  - let videobuf_to_dma_contig() return dma_addr_t
  - implement __videobuf_sync()
  - return statements, white space and other minor fixes
