===============
commit 58d4d3c976b33784a1443c446a3d7203bf2153f0 upstream.
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")
Fixes: d6173df35f ("ASoC: si476x: Remove custom register I/O implementation")
