Subject: [PATCH] kprobes: Remove an unneeded condition
Date: Tue, 21 Mar 2017 20:43:48 +0000	[thread overview]
Message-ID: <20170321204348.GD22118@mwanda> (raw)

We know that "addr" is non-NULL here so there is no need to check if
"addr + offset" is NULL.

Signed-off-by: Dan Carpenter <dan.carpenter@oracle.com>
