Hi,
I had make install a module for a dvb usb box which writen by my self. But this one didn't have real frontend ops and tuner ops.These functions did nothing but return 0.
Like this
static int demo_fe_init(struct dvb_frontend *fe)
{
return 0;
}
After the usb box removed from linux, the DVB system called demo_fe_release and demo_tu_release, sofar that seems very good！ But, I can't rmmod this module normally. It showed "ERROR: Module dvb_usb_dvbusb_demo is in use".This error is diffrent with "ERROR: Module dvb_usb is in use by dvb_usb_dvbusb_demo"
How can i rmmod this module with out reboot Linux.
thanks
