3547 | * of course means that if we set up the | |
3548 | * bottom field in the above code that we'll | |
3549 | * actually skip a field. But that's OK. | |
3550 | * Having processed only a single buffer this | |
3551 | * time, then the next time around the first | |
3552 | * available buffer should be for a top field. | |
3553 | * That will then cause us here to set up a | |
3554 | * top then a bottom field in the normal way. | |
3555 | * The alternative to this understanding is | |
3556 | * that we set up the second available buffer | |
3557 | * as a top field, but that's out of order | |
3558 | * since this driver always processes the top | |
3559 | * field first - the effect will be the two | |
3560 | * buffers being returned in the wrong order, | |
3561 | * with the second buffer also being delayed | |
3562 | * by one field time (owing to the fifo nature | |
3563 | * of videobuf). Worse still, we'll be stuck | |
3564 | * doing fields out of order now every time | |
3565 | * until something else causes a field to be | |
3566 | * dropped. By effectively forcing a field to | |
3567 | * drop this way then we always get back into | |
