Commit b6f3fc005a2c ("ASoC: simple-card-utils: fixup asoc_simple_card_get_dai_id() counting") changed endpoint parsing for asoc_simple_card_get_dai_id(), but it seems the old code is correct. This code should follow the generic binding documentation for Documentation/devicetree/bindings/graph.txt that allows multiple endpoints for each port.
