DVBSky T980C ci not working with kernel 4.x

DVBSky T980C ci not working with kernel 4.x

[Timo Helkiö]

Hi


Common interface in Dvbsky T980C is not working with Ubuntu 15.10 kernel 
4.2.0 and vanilla kernel 4.6 and latest dvb-drivers from Linux-media 
git. With Ubuntu 15.04 and kernel 3.19 it is working. I have tryid to 
find differences in drivers, but my knolege of c it is not possible. 
Erros message is "invalid PC-card".

I have also Tevii S470 with same PCIe bridge Conexant cx23885.

How to debug this? I can do minor changes to drivers for testing it.

Does this card work with the media code from dvbsky.net from kernel 4.x?

the code from dvbsky works, specificaly this one:
http://www.dvbsky.net/download/linux/media_build-bst-151028.tar.gz

i contacted dvbsky a month or two ago and complained about their old 
drivers no longer working on newer kernels, then i got the above link 
and CI works.

but, i would prefer a working solution using the official code that is 
in the kernel or the "proper" media_build.

there is several reports of this card being broken but unfortunately it 
looks like noone can fix it.
unfortunately i dont know enough to debug kernel drivers or how the 
linux kernel works.

Yes, with drivers from dvbsky.net CI is working, but other card 
TechnoTrend TT-connect CT2-4650 CI stoped working totaly. It has same 
chips as Dvbsky T980C:

Demodulator: Silicon Labs Si2168-A20
Tuner: Silicon Labs Si2158-A20
CI chip: CIMaX SP2HF

Dvbsky-based driver uses precompiled sit2_op.o insteadt of s12168 module.

Who could merge these?
