Description

In the Linux kernel, the following vulnerability has been resolved:<br /> <br /> NTB: fix possible name leak in ntb_register_device()<br /> <br /> If device_register() fails in ntb_register_device(), the device name<br /> allocated by dev_set_name() should be freed. As per the comment in<br /> device_register(), callers should use put_device() to give up the<br /> reference in the error path. So fix this by calling put_device() in the<br /> error path so that the name can be freed in kobject_cleanup().<br /> <br /> As a result of this, put_device() in the error path of<br /> ntb_register_device() is removed and the actual error is returned.<br /> <br /> [mani: reworded commit message]
