3754 | * and set up the bottom field in the logic | |
3755 | * below. Don't ever do the top field. This | |
3756 | * of course means that if we set up the | |
3757 | * bottom field in the above code that we'll | |
3758 | * actually skip a field. But that's OK. | |
3759 | * Having processed only a single buffer this | |
3760 | * time, then the next time around the first | |
3761 | * available buffer should be for a top field. | |
3762 | * That will then cause us here to set up a | |
3763 | * top then a bottom field in the normal way. | |
3764 | * The alternative to this understanding is | |
3765 | * that we set up the second available buffer | |
3766 | * as a top field, but that's out of order | |
3767 | * since this driver always processes the top | |
3768 | * field first - the effect will be the two | |
3769 | * buffers being returned in the wrong order, | |
3770 | * with the second buffer also being delayed | |
