 * This function is intended to be used as a VIDIOC_DQBUF ioctl handler.

 * This function is intended to be used as a VIDIOC_DQBUF ioctl handler.

 *

 *

 * The v4l2_buffer structure passed from userspace is first sanity tested. If

 * Wait until a buffer is ready to be dequeued, remove it from the queue and

 * sane, the buffer is then processed and added to the main queue and, if the

 * copy its information to the v4l2_buffer structure.

 * queue is streaming, to the IRQ queue.

 *

 *

 * Before being enqueued, USERPTR buffers are checked for address changes. If

 * If the nonblocking argument is not zero and no buffer is ready, return

 * the buffer has a different userspace address, the old memory area is unlocked

 * -EAGAIN immediately instead of waiting.

 * and the new memory area is locked.

 *

 * If no buffer has been enqueued, or if the requested buffer type doesn't match

 * the queue type, return -EINVAL.
