Will removing the v-ape-supply property cause regressions in the
ux500-msp-i2s driver?

Looking at sound/soc/ux500/ux500_msp_dai.c:ux500_msp_drv_probe(), it
unconditionally requests this regulator:

        drvdata->reg_vape = devm_regulator_get(&pdev->dev, "v-ape");
        if (IS_ERR(drvdata->reg_vape)) {

Will this missing supply cause the regulator framework to fall back to a
dummy regulator (emitting a warning) or return an error and break the
driver probe entirely?

Ooops I'll add a patch removing that so the driver just uses the power
domain.
