+ * 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
