[PATCH tty-next 0/1] premature tty_port destruction diagnostic

[Peter Hurley]

Hi Greg,

Now that the bluetooth rfcomm tty refcounting is fixed in linux-next,
I'd like to add this patch which aborts tty_port destruction if the
tty has not yet been released. At least this problem won't show up
as some random memory corruption (as was happening with rfcomm).

Even though this only WARNs, the machine is likely to crash anyway
because the port indexes will not be in sync; the tty layer will
assume the port has been destructed while the tty_port obviously
has not.

Regards,
