Johan Hovold 3fd682d461 ipack: ipoctal: fix tty-registration error handling ... commit cd20d59291 upstream. Registration of the ipoctal tty devices is unlikely to fail, but if it ever does, make sure not to deregister a never registered tty device (and dereference a NULL pointer) when the driver is later unbound. Fixes: 2afb41d9d3 ("Staging: ipack/devices/ipoctal: Check tty_register_device return value.")
