Summary
In the Linux kernel, the following vulnerability has been resolved: drivers: dio: fix possible memory leak in dio_init() If device_register() returns error, the 'dev' and name needs be freed. Add a release function, and then call put_device() in the error path, so the name is freed in kobject_cleanup() and to the 'dev' is freed in release function.
