ASoC: tlv320dac33: fix regression by adding back .read/.write
commit c4305af43a8 ("ASoC: use internal reg_cache on tlv320dac33") removed .read/.write from driver, but it might breaks non-regmap driver, because ALSA SoC framework might call it. To fix this regression, this patch back .read/.write Signed-off-by: Kuninori Morimoto <kuninori.morimoto.gx@renesas.com> Signed-off-by: Mark Brown <broonie@kernel.org>
