Subject: [PATCH BlueZ 03/20] audio/control: Use service user_data for private data
Date: Mon,  8 Jul 2013 17:10:09 +0300	[thread overview]
Message-ID: <1373292626-3776-4-git-send-email-luiz.dentz@gmail.com> (raw)
In-Reply-To: <1373292626-3776-1-git-send-email-luiz.dentz@gmail.com>

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

This remove the need of forward declaration of struct control and prepare
for a complete removal of struct audio_device.
