Don't generate an error message when devm_gpiod_get fails with
-EPROBE_DEFER.

Change looks good generally, but please make it like this to reduce
the amount of PTR_ERR():

ret = PTR_ERR_OR_ZERO(gpio_restart->reset_gpio)
if (ret) {
    if (ret != -EPROBE_DEFER)
        dev_err(...)
    return ret;
}

Thanks,

-- Sebastian
