[PATCH] prevent oops from read of proc entry for tty drivers

[Stephen Hemminger]

There are /proc handles there setup by proc_tty_register_driver, but there is
no module ownership association, so anything that reads after module unload
will blow.  Fix is to propagate owner of tty_driver to proc entry.
