[alsa-devel] [PATCH] ASoC: soc-core: call snd_soc_runtime_set_dai_fmt() before soc_new_pcm()

[Kuninori Morimoto]

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

Current snd_soc_runtime_set_dai_fmt() is called after
soc_probe_link_dais(). this means snd_soc_dai_set_fmt() will be
called after soc_new_pcm().

Before appling 1efb53a220b78fdfdbb97b726a2156713e75bdab
(ASoC: simple-card: Remove support for setting differing DAI formats)
simple-card user had (1) snd_soc_dai_set_fmt() -> soc_new_pcm(),
but, after that it is (2) soc_new_pcm() -> snd_soc_dai_set_fmt().
At least rsnd driver is assuming (1) pattern.

This patch move snd_soc_dai_set_fmt() into soc_probe_link_dais()
after the dai_link->init section to solve this issue.

This patch solves my issue, but I don't know how much effect it has
to other drivers.
