From 827afdf093cce59bbbf9dc9f1c2eab86e2232b9e Mon Sep 17 00:00:00 2001 From: Adrian Bunk <bunk@kernel.org> Date: Tue, 16 Oct 2007 23:29:25 -0700 Subject: [PATCH] n_hdlc.c: fix check-after-use The Coverity checker spotted that we'd have already oops'ed if "tty" was NULL. Since "tty" can't be NULL when we reach this line of code this patch removes the NULL check.
