Subject: [PATCH 02/15] perf jit: Remove some no-op error handling
Date: Mon, 18 Jul 2016 20:33:05 -0300 [thread overview]
Message-ID: <1468884798-14932-3-git-send-email-acme@kernel.org> (raw)
In-Reply-To: <1468884798-14932-1-git-send-email-acme@kernel.org>
From: Dan Carpenter <dan.carpenter@oracle.com>
The 'info.e_machine' struct member is an uint16_t so 'm' is never less
than zero. It looks like this was maybe left over code from earlier
versions so I've just removed it.
