ASoC: rsnd: disable SRC.out only when stop timing
commit b761bf272bce6dff4d8a7ccf4385c9f3d4018094 upstream. Because SRC is connected to DMA and DMA want to keep dreq when stop timing. This patch makes SRC stop SRC.out only when stop timing. And it stops both SRC.out/SRC.in when quit timing Signed-off-by: Kuninori Morimoto <kuninori.morimoto.gx@renesas.com> Signed-off-by: Mark Brown <broonie@kernel.org> Signed-off-by: Thong Ho <thong.ho.px@rvc.renesas.com> Signed-off-by: Nhan Nguyen <nhan.nguyen.yb@renesas.com> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
