| * bottom field in the above code that we'll |
| * actually skip a field. But that's OK. |
| * Having processed only a single buffer this |
| * time, then the next time around the first |
| * available buffer should be for a top field. |
| * That will then cause us here to set up a |
| * top then a bottom field in the normal way. |
| * The alternative to this understanding is |
| * that we set up the second available buffer |
| * as a top field, but that's out of order |
| * since this driver always processes the top |
| * field first - the effect will be the two |
| * buffers being returned in the wrong order, |
| * with the second buffer also being delayed |
| * by one field time (owing to the fifo nature |
| * of videobuf). Worse still, we'll be stuck |
| * doing fields out of order now every time |
| * until something else causes a field to be |
| * dropped. By effectively forcing a field to |
| * drop this way then we always get back into |
| * sync within a single frame time. (Out of |
