From f11afb61247016162aa92225a337c1575556c9d9 Mon Sep 17 00:00:00 2001 From: Jiri Slaby Date: Thu, 18 Oct 2012 22:26:29 +0200 Subject: TTY: devpts, do not set driver_data The goal is to stop setting and using tty->driver_data in devpts code. It should be used solely by the driver's code, pty in this case. Now driver_data are managed only in the pty driver. devpts_pty_new is switched to accept what we used to dig out of tty_struct, i.e. device node number and index. This also removes a note about driver_data being set outside of the driver.
