2.6.32-longterm review patch. If anyone has any objections, please let us know.
------------------ From: Jiri Slaby <[email protected]> commit 6960f40a954619857e7095a6179eef896f297077 upstream. Make sure that we check the return value of tty_port_tty_get. Sometimes it may return NULL and we later dereference that. The only place here is in kobil_read_int_callback, so fix it.
