Description
In the Linux kernel, the following vulnerability has been resolved: tty: goldfish: Use tty_port_destroy() to destroy port In goldfish_tty_probe(), the port initialized through tty_port_init() should be destroyed in error paths.In goldfish_tty_remove(), qtty->port also should be destroyed or else might leak resources. Fix the above by calling tty_port_destroy().
