Hi Annti,
I generated a patch using git diff 8a56b6b..5786103 on your branch and
applied it to the current media_build tree, because I'm more experienced
with it as compared to building my own kernels. After installing it, I
removed m88ts2022.ko.gz shipped with my kernel and ran depmod -a. After
a power-down/up cycle I can see
/dev/dvb/adapter{0,1}/{demux,dvr,frontend,net}0. Unfortunately the
frontends time out while tunning to a channel.

It looks as if the firmware dvb-fe-ds3103.fw is not getting downloaded
with your patch. I thought there shouldn't be nodes in /dev/dvb/ in this
case?
Looks strange as firmware is not downloaded. It is downloaded on when
first tuning attempt is done, so nodes are created in any case. TS2020
tuner is detected correctly, which looks somehow promising. Could you
test my patches again as I have done some changes (tree is rebased).
To roll back I reinstalled the old tree, moving the original
m88ts2022.ko.gz back in and running depmod -a. Rebooting didn't bring
the S952 up, it said:
Mär 24 10:39:07 htpc kernel: Unable to find Montage chip
Mär 24 10:39:07 htpc kernel: cx23885[0]: frontend initialization failed
Mär 24 10:39:07 htpc kernel: cx23885_dvb_register() dvb_register failed
err = -22
Mär 24 10:39:07 htpc kernel: cx23885_dev_setup() Failed to register dvb
adapters on VID_B
So maybe it left it in a strange/undefined state? I had to poweroff the
machine and start from there. Afterwards everything is fine again.

Antti
Thanks,
Ole

Very much appreciated, thanks Antti! Let me know, if you need someone to

Could you test that tree?
http://git.linuxtv.org/cgit.cgi/anttip/media_tree.git/log/?h=ts2020
git clone -b ts2020 git://linuxtv.org/anttip/media_tree.git
then compile and install whole kernel
