As we know, in linux dvb subsystem, we use dvb_attach() macro to return a dvb_frontend pointer.
But in my driver, there are some unexpected things happening.
In mydriver_frontend_attach() function, it return an available pointer, but in dvb_usb_adapter_frontend_init() function, when checking the adap->fe field, just as follows:
if (adap->props.frontend_attach(adap) == 0 && adap->fe != NULL) {
.............................
} else
err("no frontend was attached by '%s'",adap->dev->desc->name);
I myself checked the adap->fe field, it becomes NULL.
So my frontend is not attached actually.
Can someone give me advice about this issue??????
Thank you in advance.
