Subject: [PATCH 1/1] ASoC: tlv320aic32x4: use dev_err_probe() for regulators

From: Matthias Schiffer <matthias.schiffer@...tq-group.com>

Avoid error messages like the following when the regulators have not
been probed yet:

    tlv320aic32x4 0-0018: Missing supply 'iov'
    tlv320aic32x4 0-0018: Failed to setup regulators
