From 8a484719c790772bc51c87c56323611752361bef Mon Sep 17 00:00:00 2001
From: Oliver Endriss <o.endriss@gmx.de>
Date: Mon, 10 Jan 2011 06:36:14 -0300
Subject: [media] ngene: Clean-up driver initialisation (part 1)

If tuner initialisation failed, the frontend node was not removed.
When the frontend was opened, a kernel oops occurred...

This is the first step to improve error handling during initialisation.

Subject: [media] ngene: CXD2099AR Common Interface driver

Driver for the Common Interface Controller CXD2099AR.
Supports the CI of the cineS2 DVB-S2.

For now, data is passed through '/dev/dvb/adapterX/sec0':
- Encrypted data must be written to 'sec0'.
- Decrypted data can be read from 'sec0'.
- Setup the CAM using device 'ca0'.

Subject: [media] Move CI cxd2099 driver to staging

This driver is abusing the kernel<=>userspace API, due to the lack of a
proper solution for it. A discussion were done at:
	http://www.mail-archive.com/linux-media@vger.kernel.org/msg22196.html
But there's not a solution for it yet. So, move the driver to staging, while
we don't have a final solution.
