In the linux kernel, the following vulnerability has been resolved ntbfix possible name leak in ntb_register_device() if device_register() failsin ntb_register_device(), the device name allocated by dev_set_name()should be freed. as per the comment in device_register(), callers shoulduse put_device() to give up the reference in the error path. so fix this bycalling put_device() in the error path so that the name can be freed inkobject_cleanup(). as a result of this, put_device() in the error path ofntb_register_device() is removed and the actual error is returned.
