[alsa-devel] [PATCH] ASoC: audio-graph-scu-card: fix balance of of_node_get/put()
From: Kuninori Morimoto kuninori.morimoto.gx@renesas.com
audio-graph-scu-card with CONFIG_OF_DYNAMIC triggers several errors at kernel boot, like the following one OF: ERROR: Bad of_node_put() on /soc/sound@ec500000/ports/port@1
This patch doesn't call unnecessary of_node_put() which was called in other function (= of_graph_get_port_parent(), of_phandle_iterator_next())

Tony Lindgren's patch solved this issue, too This patch is no longer needed
