(2nd try, this should be now in "plain text" instead of HTML)
Thanks for your "howto" on making a proper patch.
After a "make commit" in my local v4l-dvb tree, and filling in the
template I got the following output.
I confess I do not know if this has now ended up somewhere in
linuxtv.org or that it is just local.
However, here it is:

Separate tuning table for DVB-C solves tuning problem at 388MHz.
From: Klaas de Waal <klaas.de.waal at gmail.com>
TechnoTrend C-1501 DVB-C card does not lock on 388MHz.
I assume that existing frequency table is valid for DVB-T. This is suggested
by the name of the table: tda827xa_dvbt.
Added a table for DVB-C with the name tda827xa_dvbc.
Added runtime selection of the DVB-C table when the tuner is type FE_QAM.
This should leave the behaviour of this driver with with DVB_T tuners unchanged.
This modification is in file tda827x.c
The tda827x.c gives the following warning message when debug=1 :
tda827x: tda827x_config not defined, cannot set LNA gain!
Solved this by adding a tda827x_config struct in budget-ci.c.

I have attached the result of "hg diff > tda827x_dvb-c_tuning_table.patch.
Patch is based on the "hg clone" done 23 march.
Tested again, now with Linux kernel 188.8.131.52.
