[alsa-devel] [PATCH 16/19] ASoC: rsnd: add probe/remove callback on rsnd_mod_ops

[Kuninori Morimoto]

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

Each rsnd mod needs specific probe method,
and its best timing is DAI probe timing.
But current code runs it mod probe timing.
This patch adds new probe/remove callback to solve it.
