Since the current code has the following, we have to set the active_low...
However, the code is unreadable, I think. So, I will modify the code.
/* check GPIO determining if USB function should be enabled */
if (priv->dparam.enable_gpio) {
gpio_request_one(priv->dparam.enable_gpio, GPIOF_IN, NULL);
ret = !gpio_get_value(priv->dparam.enable_gpio);
gpio_free(priv->dparam.enable_gpio);
if (ret) {
dev_warn(&pdev->dev,
"USB function not selected (GPIO %d)\n",
priv->dparam.enable_gpio);
ret = -ENOTSUPP;
goto probe_end_mod_exit;
}
}
