From a50f724a432997321cabb6c9e665c28e34850f78 Mon Sep 17 00:00:00 2001 From: Jiri Slaby Date: Mon, 30 Jan 2012 21:14:31 +0100 Subject: [PATCH] TTY: pty, remove superfluous ptm test The code looks like: if (tty->driver->subtype == PTY_TYPE_MASTER) { ... if (tty->driver == ptm_driver) But the second if is superfluous because only the ptm_driver is of PTY_TYPE_MASTER subtype. Also we can remove the #if now because devpts_pty_kill is defined as an empty function for non-CONFIG_UNIX98_PTYS configs.
