Subject: [Qemu-devel] [PATCH 3/3] opts: remove redundant check for NULL parameter
Date: Mon, 14 May 2018 18:19:13 +0100	[thread overview]
Message-ID: <20180514171913.17664-4-berrange@redhat.com> (raw)
In-Reply-To: <20180514171913.17664-1-berrange@redhat.com>

No callers of get_opt_value() pass in a NULL for the "value" parameter,
so the check is redundant.
