Yang Yingliang 195fb76dc4 Drivers: hv: vmbus: fix possible memory leak in vmbus_device_register()
[ Upstream commit 25c94b0515 ]

If device_register() returns error in vmbus_device_register(),
the name allocated by dev_set_name() must be freed. As comment
of device_register() says, it should use put_device() to give
up the reference in the error path. So fix this by calling
put_device(), then the name can be freed in kobject_cleanup().
