  "message": "usb: cdc-acm: Decrement tty port\u0027s refcount if probe() fail\n\nThe cdc-acm driver does not have a refcount of itself, but uses a\ntty_port\u0027s refcount. That is, if the refcount of tty_port is \u00270\u0027, we\ncan clean up the cdc-acm driver by calling the .destruct()\ncallback function of struct tty_port_operations.\n\nThe problem is the destruct() callback function is not called if\nthe probe() fails, because tty_port\u0027s refcount is not zero. So,\nadd tty_port_put() when probe() fails.\n\nSigned-off-by: Jaejoong Kim \u003cclimbbb.kim@gmail.com\u003e\nAcked-by: Oliver Neukum \u003coneukum@suse.com\u003e\nSigned-off-by: Greg Kroah-Hartman \u003cgregkh@linuxfoundation.org\u003e\n",
