Effectively the device is passed it is just implicit. If you look
where the regulator is actually registered in soc-dapm.c
case snd_soc_dapm_regulator_supply:
w->regulator = devm_regulator_get(dapm->dev, w->name);
if (IS_ERR(w->regulator)) {
You see we are requesting the regulator with the dapm device,
which will correspond to the CODEC.
Thanks,
