Would it be acceptable to check if spi->irq interrupt number is equal to
fwnode_irq_get_byname(dev_fwnode(dev), "rdy")?

If not, a message could be passed that specifies either that "rdy" is
needed or that it must be placed first.


Another alternative would be adding irq to ad_sigma_delta_info so a
driver could specify the desired interrupt to be used for conversions.
