[alsa-devel] ASoC: fix regression by adding back .read/.write

[Kuninori Morimoto]

Hi Mark

As Tony mentioned in "PM regression in next" mail thread,
below drivers need .read/.write back on codec driver.
twl4030/twl6040 side will be fixed by Tony's patch,
thus, I post for remains.

	sound/soc/codecs/cx20442.c
	sound/soc/codecs/tlv320dac33.c
	sound/soc/codecs/twl4030.c
	sound/soc/codecs/twl6040.c
	sound/soc/codecs/uda1380.c

Because of this, my posted codec/platform conversion patch-set will
have conflict on above drivers.
I'm happy to post v2 patch for these when you accepted that series.

This .read/.write callback is implemented in Codec driver side only.
We need it in Component side too.
Last patch is for it.

Best regards
