Hi Thierry,
And thanks a lot for your patch. I've now updated the
Cinergy T2 driver patch with your remote control cleanup.

Ok, the attached version of the patch does remove the old driver.

In my understanding this is a bug in the dvb-usb-framework that cannot
be fixed in Cinergy T2 driver. I checked that if you DON'T define the
menuconfig option:
"Load and attach frontend and tuner driver modules as needed" ie.
the CONFIG_MEDIA_ATTACH
The framework will use a different version of the function called
"dvb_frontend_detach" and thefore it will not call the symbol_put_addr
on linux/drivers/media/dvb/dvb-core/dvb_frontend.c line 1220.
With this option deselected the module reference count seems to stay
in sane values.

Heh,heh :)
Regards,
Tomi Orava
