Subject: [PATCH BlueZ 2/2 v2] attrib: Don't attempt to unregister event id 0
Date: Mon, 28 Jan 2013 15:44:01 -0600	[thread overview]
Message-ID: <1359409441-21066-2-git-send-email-luiz.dentz@gmail.com> (raw)
In-Reply-To: <1359409441-21066-1-git-send-email-luiz.dentz@gmail.com>

From: Luiz Augusto von Dentz <luiz.von.dentz@intel.com>

Id 0 is considered invalid so the code should not even try to lookup for
it in the event list instead print a warning and return FALSE
immediatelly.
