The race I think happens should only happen after the first device is added to the cx8802_devlist and while the cx88-dvb module is probing devices a second device is being added to the cx8802_devlist with a pointer not properly set yet. (Of course, I'm not sure why Mauro's recent change didn't work for Gregoire.) As for Gregoire's tuning problem, I haven't looked into that, nor do I have the hardware to play with. Regards.
