There's no sense on keeping it on 2.6.38, as nobody is using it

As two deprecated drivers still need it, move it to their internal

ivtv_write_vbi() is used for both VBI data that came from the

it did not use copy_from_user() for reading the VBI data from the
user buffers.
This change adds a new version of the function,
ivtv_write_vbi_from_user(), that uses copy_from_user() to read the VBI

- Gigaware model 25-234 (0c45:628f);
- Logitech Messenger Plus (046d:08f6).

What happens is that several devices don't need to save some bandwidth

Also, as pointed by Hans de Goede <hdegoede@redhat.com>, the logic
that implements the bandwidth reservation for audio is broken, since
it will reduce the alt number twice, on devices with audio.

[media] rc-core: add loopback driver
This patch adds a loopback driver to rc-core which I've found useful for
running scripted tests of different parts of rc-core without having to
fiddle with real hardware.
Basically it emulates hardware with a learning and a non-learning
receiver and two transmitters (which correspond to the two
receivers). TX data that is sent is fed back as input on the
corresponding receiver, which allows for debugging of IR decoders,
keymaps, etc.

[media] rc: fix sysfs entry for mceusb and streamzap
When trying to create persistent device names for mceusb and streamzap
devices, I noticed that their respective drivers are not creating the rc
device as a child of the USB device. Rather it creates it as virtual
device. As a result, udev cannot use the USB device information to
create persistent device names for event and lirc devices associated
with the rc device. Not having persistent device names makes it more
difficult to make use of the devices in userspace as their names can
change.
Forward-ported to media_tree staging/for_v2.6.38 and tested with
both streamzap and mceusb devices:

making a patch and sending it here. So here's the patch against
staging/2.6.37-rc1 branch (the tutorial recommends to include it as
plain text but if it's the case I can surely send as an attachment):
Several comments on the patch:
1. Both users on the official Gotview forum and support said that PCI
DVD3 is very similar to Yuan MPC718 card so the main part of code is
taken from Yuan configuration. Some users reported it to work properly.
2. Everything is being initialized correctly including analog, dvb,
radio and alsa parts. Analogue part and alsa virtual card is tested by
myself using original Gotview card.

[media] IX2505V: i2c transfer error code ignored

This looks like a typing error using (ret = 1) instead of correct (ret == 1).
