I pushed up a few patches about an hour ago, tip changeset is: c0f7293d1ac6 - m920x: move qt1010_tuner_attach function into qt1010.h if you do, 'hg heads', is this the revision that you're using?

Is the problem described below my fault? Can you test the current tree on your device and reproduce this error? Patrick has given his Ack on the new dvb-usb module...
