[alsa-devel] [PATCHv2 1/4] ASoC: tlv320aic3x: Move regulator management from i2c to soc domain

[Jarkko Nikula]

It will be easier to keep regulator enable/disable calls in sync when dynamic
regulator management is added if regulator management is moved from
aic3x_i2c_probe/_remove to aic3x_probe/_remove.
