Subject: ASoC: si476x: Fix IO setup
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=58d4d3c976b33784a1443c446a3d7203bf2153f0;p=GitHub%2FLineageOS%2FG12%2Fandroid_kernel_amlogic_linux-4.9.git

ASoC: si476x: Fix IO setup

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")
