Subject: [PATCH 02/12] tty: Remove !tty check from free_tty_struct()
Date: Fri, 27 Nov 2015 21:25:47 -0500 [thread overview]
Message-ID: <1448677557-16420-3-git-send-email-peter@hurleysoftware.com> (raw)
In-Reply-To: <1448677557-16420-1-git-send-email-peter@hurleysoftware.com>
free_tty_struct() is never called with NULL tty; the two call sites
would already have faulted on earlier access.
