From eab4f5af6b07009d1fc48bac5f3215c0cbfb2fc3 Mon Sep 17 00:00:00 2001 From: Alan Cox Date: Tue, 1 Jun 2010 22:52:52 +0200 Subject: tty: serial - fix tty back references in termios One or two drivers go poking back into the tty from the termios setting routine in unsafe ways. We don't need to pass the tty down because the [ab]users are just using it to get at things they can get at anyway. This leaves low_latency setting to sort out along with set_ldisc use.
