I think that we shouldn't fail if the property is absent, but default
to the mapping that is currently hard coded in the driver. Otherwise
we would break existing users.
I don't think there is a risk of breaking existing users. On platforms
where the leds-ns2 driver is used, DTB will be updated with the kernel
image. Moreover, removing the hard coded mapping is a nice clean-up.
Let me know if you still want me to add a fallback.
Since you modify also dts file in this patch set this is OK.
You can keep this part as is.
