Subject: [PATCH 24/33] NFC: Forbid SSAP binding to a not well known LLCP service
Date: Fri,  6 Jul 2012 22:09:44 +0200	[thread overview]
Message-ID: <1341605393-32056-25-git-send-email-sameo@linux.intel.com> (raw)
In-Reply-To: <1341605393-32056-1-git-send-email-sameo@linux.intel.com>

With not Well Known Services there is no guarantees as to which
SSAP the server will be listening on, so there is no reason to
support binding to a specific source SAP.
