From f64ac9830b2a2455208ee023f6bac480ae159db4 Mon Sep 17 00:00:00 2001 From: Dan Carpenter Date: Thu, 12 Aug 2010 13:48:57 -0700 Subject: [PATCH] ip2: remove unneeded NULL check We don't pass NULL tty pointers to the close function, and anyway we already dereferenced it at this point. This check can be removed. Signed-off-by: Dan Carpenter Cc: "Michael H.
