it's enough, I told him that I'll look at it and try to get some other
people involved if it really breaks something it should get stated
out; and I'll refuse any further help if he starts to write any more
abusive mail.

So to his proposal:

the whole noise is about following Makefile patch:
-obj-$(CONFIG_DVB_BT8XX) += bt878.o dvb-bt8xx.o dst.o dst_ca.o
+obj-$(CONFIG_DVB_BT8XX) += bt878.o dvb-bt8xx.o
+obj-$(CONFIG_DVB_DST) += dst.o
+obj-$(CONFIG_DVB_DST_CA) += dst_ca.o

that symbol_request is unable to return a valid pointer if DST an
DST_CA aren't selected should be ok because this would only happen if
someone didn't compile them in (an appropriate error message should be
added for that)

I'm trying to look closer at this issue with some other developers, if
it's really that easy to split off the dst module from the bt* objects
without breaking anything, to me the direction this patch goes seems
to be ok, some people stated out that there are problems so I'll try
to get more information about that.
