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

commit 39b5a0f80c07f ("ASoC: cx20442: don't use reg_cache") 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. and also this patch uses cx20442 internal reg_cache which is needed for .read/.write.

From: Kuninori Morimoto kuninori.morimoto.gx@renesas.com Date: Tue, 16 Jan 2018 02:00:59 +0000 Subject: [PATCH] ASoC: add Component level .read/.write

In current ALSA SoC, Codec only has .read/.write callback. Codec will be merged into Component in next generation ALSA SoC, thus current Codec specific feature need to be merged into it. This is glue patch for it.
