Hi Manu, hi Steven!
It seems an update of dvb-core breaks tuning of cx24123.
After updating to latest v4l-dvb the nova-s plus card just did no longer lock
to any channel. So I bisected it, and found this commit:
changeset: 9344:aa3a67b658e8
parent: 9296:e2a8b9b9c294

summary: DVB-Core update
http://linuxtv.org/hg/v4l-dvb/rev/aa3a67b658e8
It basically did update the dvb-kernel-thread and enhanced the code using
get_frontend_algo.
The codepath when get_frontend_algo returns *_ALGO_HW stayed the same, only
one line got removed: params = &fepriv->parameter
Just re-adding that line made my card working again. Either this was lost, or
the last two lines using "params" should also be converted to directly
use "&fepriv->parameters".
Regards
Matthias
