[alsa-devel] [asoc:topic/dai-id 1/1] sound/soc/soc-core.c:4054:9: error: implicit declaration of function 'of_graph_get_port_parent'

[Kuninori Morimoto]

Hi Mark

This and below kbuild report are all related to of-graph

	Subject: [linux-next:master 1926/2534] sound/soc/sh/rcar/core.c:891:8: error: implicit declaration of function 'of_graph_get_endpoint_count'
	Subject: [linux-next:master 1927/2534] sound/soc/sh/rcar/ssi.c:888:14: error: implicit declaration of function 'of_graph_get_remote_endpoint'

and it seems these are not based on mark/topic/of-graph branch.
Maybe no problem for next merge
