Currently the modules dst.c and dst-ca.c are compiled in connection with dvb-bt8xx.c by default like a "siamese birth".
As the Pinnacle PCTVSAT DOES NOT NEED dst.c or dst-ca.c I invented this patch to save RAM.
This is something for users, perhaps for the mm-tree, but NOTHING for the vanilla mainline at all.
I would like to invite some developpers to see this thing through and offer a more sophisticated solution that
a. saves RAM
b. is not getting rid of support for dst.c and dst-ca.c
