Subject[PATCH] dt-bindings: leds: class-multicolor: reference class directly in multi-led node
Date
The leds/common.yaml is referenced directly in each LED node, which
leads to people doing the same with leds/leds-class-multicolor.yaml.
This is not correct because leds-class-multicolor.yaml defined multi-led
property and its children. Some schemas implemented this incorrect.

Rework this to match same behavior common.yaml, so expect the multi-led
node to reference the leds-class-multicolor.yaml. Fixing allows to add
unevaluatedProperties:false.

This will conflict with any new users of leds-class-multicolor, e.g.:
https://lore.kernel.org/all/20220623115631.22209-4-peterwu.pub@gmail.com/

The new users should be updated to match the usage introduced here.
