You should also drop the following code in the same function:

	/* Allow IDMAC interweave but enforce field order from source. */
	if (V4L2_FIELD_IS_INTERLACED(pixfmt->field)) {
		switch (pixfmt->field) {
		case V4L2_FIELD_SEQ_TB:
			pixfmt->field = V4L2_FIELD_INTERLACED_TB;
			break;
		case V4L2_FIELD_SEQ_BT:
			pixfmt->field = V4L2_FIELD_INTERLACED_BT;
			break;
		default:
			break;
		}
	}
