ASoC: rsnd: add rsnd_src_get_in/out_rate()
SRC will convert rate, and then, CMD and SSI want to know its rate (= SRC.in / SRC.out) for each purpose. Current driver is supporting only Playback, but SRC+Capture support needs more flexibility. This patch adds rsnd_src_get_in/out_rate() for it. Signed-off-by: Kuninori Morimoto <kuninori.morimoto.gx@renesas.com> Signed-off-by: Mark Brown <broonie@kernel.org>
