Yes you had some code in there, just that you know some linuxtv people
(I don't want to name them here) wrote that the em2880-dvb module is
just wrong because of what you did. Since I know about the DVB
framework now I have to say that these people who claimed that it's
wrong have had no idea about the framework back then and that it was
fine what you did.
It is not you who went through such discussions, since I managed the
code I received these comments and instead that these people sent some
patches they just claimed that it was bad and wrong.
This community needs a change if it wants to survive and get companies
onto the boat, right now it's controlled by a few wannabes who
missleaded me in history but who never sent any patches against the
repository either to improve the parts which were in question.

hmm? if it's related to the code on mcentral.de please post a
bugreport or feature request; maybe make kernel-links is what you're
looking for, please give me some more details about this.
