Not knowing much about camss and by just a quick look at the driver,
should:
ret = camss_configure_pd(camss);
if (ret < 0) {
dev_err(dev, "Failed to configure power domains: %d\n", ret);
return ret;
}
Be changed to jump to an error label and unregister the media entities
in case of failure in probing the power domains ?
