[PATCH] ASoC: si476x: Fix IO setup

[Lars-Peter Clausen]

The si476x is a MFD device and the CODEC driver is using the regmap struct of
the parent device, hence automatic IO setup will not work and we need to
manually call snd_soc_codec_set_cache_io(). The issue was introduced commit
d6173df35f ("ASoC: si476x: Remove custom register I/O implementation")

Applied, thanks.  Please if you're listing which commit is being fixed
