However, -mm itself is somewhat of a testing area. If I understand it correctly, the patches in v4l are only adding dvb support, and will not break anything unrelated. Is this correct? If that is correct, then it is okay for Mauro to have sent them. Now, I need to know from you whether the corresponding dvb patch to tda1004x should also be sent to -mm? IIRC, the patch that Mauro sent to -mm might depend on this dvb patch. If so, let me know, and I'll send it to akpm. Unless, of course, you think it has the potential to break other boards. In which case, let Mauro know and he can have akpm drop it from -mm until it can get some more testing in cvs. -Mike
