I've got code which adds support of GoTView PCI DVD3 Hybrid tuner in
cx18 module and Andy Walls in ivtv mailing-list gave me some advice on
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.

The patch fixes the rc-tbs-nec table after converting
drivers/media/video/cx88 to ir-core
(commit ba7e90c9f878e0ac3c0614a5446fe5c62ccc33ec).

It is also adds two missing buttons (10- and 10+) with
its definition (KEY_10CHANNELSUP and KEY_10CHANNELSDOWN).

Remote keytables had different names all over the place. Part of the fault
is due to a bad naming when rc subsystem was created, but there were lots
of old names that were still here.

Use a common standard for everything.

The struct that describes a rc mapping had an weird and long name.
We should properly name it, to make easier for developers to work
with it, and to avoid confusion.

The Remote Controller subsystem is meant to be used not only by Infra Red
but also for similar types of Remote Controllers. The core is not specific
to Infra Red. As such, rename:

	- IR_CORE to RC_CORE
	- namespace inside rc-core.c/rc-core.h

Convert the driver to use the dvb_attach macro to avoid the hard dependency
on the frontend drivers.  The hard dependecy will result in loading a
number of unused frontends, and unwanted automatic dereferencing.

This fixes a bug where unloading the mantis driver will derefence any
attached frontend twice, which will cause an oops if the same frontend is
used by another driver.

After dvb-core has called mantis-fe->stop_feed(dvbdmxfeed)
the last time (count to zero), no data should ever be copied
with dvb_dmx_swfilter() by a tasklet: the target structure
might be in an unusable state. Caller of mantis_fe->stop_feed()
assumes that feeding is stopped after stop_feed() has been
called, ie. dvb_dmx_swfilter() isn't running, and won't be called.

There is a risk that dvb_dmx_swfilter() references freed resources
(memory or spinlocks or ???) causing instabilities. Thus
tasklet_disable(&mantis->tasklet) must be called inside of
mantis-fe->stop_feed(dvbdmxfeed) when necessary.
