ASoC: rsnd: add common interrupt handler for SSI/SRC/DMA
Each Renesas sound mod (= SSI/SRC/DVC) might be called from many paths if it supports MIXer. In such case, mod <-> io is no longer 1:1 relationship. Then, interrupt handler can't use rsnd_mod_to_io(). This patch adds SSI/SRC/DMA common interrupt handler frame Signed-off-by: Kuninori Morimoto <kuninori.morimoto.gx@renesas.com> Tested-by: Keita Kobayashi <keita.kobayashi.ym@renesas.com> Signed-off-by: Mark Brown <broonie@kernel.org>
