[alsa-devel] [PATCH 3/8] ASoC: simple-scu-card: tidyup codec daifmt handling method

[Kuninori Morimoto]

From: Kuninori Morimoto <kuninori.morimoto.gx at renesas.com>

Current simple-scu-card is handling codec daifmt by using
for_each_child_of_node(), and low-level method.
Let's use of_get_child_by_name() instead it
