Subject: [PATCH BlueZ v0 5/6] scanparam: Use btd_service userdata pointer
Date: Mon, 27 May 2013 14:04:08 +0200	[thread overview]
Message-ID: <1369656249-27980-6-git-send-email-mikel.astiz.oss@gmail.com> (raw)
In-Reply-To: <1369656249-27980-1-git-send-email-mikel.astiz.oss@gmail.com>

From: Mikel Astiz <mikel.astiz@bmw-carit.de>

Avoid maintaining an internal list of probed struct scan instances by
making use of btd_service's userdata pointer.
