Subject: [PATCH] devfreq: fix double call put_device
1295 */
1296 void device_unregister(struct device *dev)
1297 {
1298 pr_debug("device: '%s': %s\n", dev_name(dev), __func__);
1299 device_del(dev);
1300 put_device(dev);
1301 }
1302 EXPORT_SYMBOL_GPL(device_unregister);
1303
device_unregister is called put_device, there is no need to call
put_device(&devfreq->dev) again.
