I think it is easy to see that the changes for the rdy-gpios support has
zero impact if the device has no rdy-gpio. Then
devm_gpiod_get_optional() returns NULL and !sigma_delta->rdy_gpiod is
true and so nothing changes.
Of course it's subjective if you agree this to be easy to see, and also
if that matters for the backport.

I've not given up hope that you agree to backport also the rdy-gpio
change yet. I won't invest the work without knowing it's used in the
end. So I'll wait until the changes are upstream and you made up your
mind. Then if the need arises, I will help.
