tty: Fix oops when scanning the polling list for kgdb Costantino Leandro found a bug in tty_find_polling_driver and provided a patch that fixed the crash but not the underlying bug. This fixes the underlying bug where the list walk corrupts the values it is using on a match but then reuses them if the open fails.
