A quick grep reveals:
mc13783.c:	codec->control_data = dev_get_regmap(codec->dev->parent, NULL);
si476x.c:	codec->control_data = dev_get_regmap(codec->dev->parent, NULL);
wm5102.c:	codec->control_data = priv->core.arizona->regmap;
wm5110.c:	codec->control_data = priv->core.arizona->regmap;
wm8997.c:	codec->control_data = priv->core.arizona->regmap;

But there might be more.
