Johan Hovold 2ad5692db7 net: hso: fix NULL-deref on disconnect regression ... Commit 8a12f88361 ("net: hso: fix null-ptr-deref during tty device unregistration") fixed the racy minor allocation reported by syzbot, but introduced an unconditional NULL-pointer dereference on every disconnect instead. Specifically, the serial device table must no longer be accessed after the minor has been released by hso_serial_tty_unregister().
