Current rsnd driver is using rsnd_kctrl_new_m/s/e function, but the differences are very few. This patch merge these rsnd_kctrl_new_m/s/e into rsnd_kctrl_new Signed-off-by: Kuninori Morimoto <kuninori.morimoto.gx@renesas.com> Tested-by: Hiroyuki Yokoyama <hiroyuki.yokoyama.vx@renesas.com> Signed-off-by: Mark Brown <broonie@kernel.org>
