[ Upstream commit c5ed1fe0801f0c66b0fbce2785239a5664629057 ]
dev_set_name() allocates memory for name, it need be freed when module exiting, call put_device() to give up reference, so that it can be freed in kobject_cleanup() when the refcount hit to 0. The vpe_device is static, so remove kfree() from vpe_device_release().
