The same `channel` node name pattern has also been set in iio/adc/adc.yaml, but this generic binding is not inherited as base for qcom,spmi-vadc bindings due to not having any other generic elements in common, besides the node name rule and reg property. Replace the .* name pattern with the `channel` literal, but leave the label property optional for bindings to choose to fall back a channel label hardcoded in the driver [2] instead.
