* NOTES:
*
- * jds -- add private data to file to keep track of iso contexts associated
- * with each open -- so release won't kill all iso transfers.
- *
- * Damien Douxchamps: Fix failure when the number of DMA pages per frame is
- * one.
- *
* ioctl return codes:
* EFAULT is only for invalid address for the argp
* EINVAL for out of range values
* ENOTTY for unsupported ioctl request

- - fixed checks for valid buffer-numbers in video1394_icotl
- - changed the ways the dma prg's are used, now it's possible to use
