[alsa-devel] [PATCH 12/16] ASoC: soc-core: self contained soc_probe_link_dais()

[Kuninori Morimoto]

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

Current soc_probe_link_dais() implementation is very half,
thus it is very difficult to read.

	for_each_comp_order(xxx) {
		for_each_card_rtds(xxx)
=>			soc_probe_link_dais(xxx);
	}

This patch does all for_each_xxx() under soc_probe_link_dais(),
and makes it to self contained.
