Subject: [PATCH 4/5] TTY: pty, remove superfluous ptm test
Date: Mon, 30 Jan 2012 21:14:31 +0100 [thread overview]
Message-ID: <1327954472-26594-4-git-send-email-jslaby@suse.cz> (raw)
In-Reply-To: <1327954472-26594-1-git-send-email-jslaby@suse.cz>
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.
