ASoC: remove unneeded dai->driver->ops check
On soc_add_dai(), it uses null_dai_ops if driver doesn't have its own ops. This means, dai->driver->ops never been NULL. dai->driver->ops check is not needed. This patch removes it. Signed-off-by: Kuninori Morimoto <kuninori.morimoto.gx@renesas.com> Signed-off-by: Mark Brown <broonie@kernel.org>
