ASoC: rsnd: Parent SSI attach is not needed if not clock master
Parent SSI is needed if it is PIN sharing and clock master, otherwise, not needed. But, whether clockk master is judged on .set_fmt, thus, it can't call rsnd_ssi_parent_attach() on .probe. Now, .pcm_new will be called after .set_fmt, so this patch reuses it at this point. Signed-off-by: Kuninori Morimoto <kuninori.morimoto.gx@renesas.com> Signed-off-by: Mark Brown <broonie@kernel.org>
