ASoC: samsung: aries_audio_probe: double of_node_put due to direct assignment without of_node_get
In aries_audio_probe(), aries_dai[0].platforms->of_node is assigned the
same pointer as aries_dai[0].cpus->of_node (from of_parse_phandle)
without calling of_node_get(). When the sound card is deregistered, the
ASoC framework calls of_node_put() on both cpus->of_node and
platforms->of_node, causing a double put on the same node and a refcount
underflow.
Add of_node_get(aries_dai[0].cpus->of_node) before the assignment.
