When the first condition is checked, my_own_frontend_attach() function is called, using dvb_attach() macro to gain the adap->fe pointer, in my driver it is successful.
But my driver still can not register any frontend to the Linux DVB core, it must for the second condition, So I think maybe this state is unsuitable here.
Maybe should be something like this:
if(adap->props.frontend_attach(adap) == 0)
if(adap->fe != NULL)
....................

So what is your opinion?

The reason is the second condition. Maybe Gcc compiler check the second condition first.
