Wonder where I got the idea that the status wasn't returned through ioctls
pointer argument, doh!
Good idea, since the select will poll for events and the events is signaled
from dvb_frontend's kernel thread on status changes:
if (fe->ops->read_status)
fe->ops->read_status(fe, &s);
if (s != fepriv->status) {
dvb_frontend_add_event(fe, s);
fepriv->status = s;
}
I'm confused however, about what the first select+read_status is for,
since it's not actually doing anything. Was the intention that it
should have triggered a retune if lock had been lost?
Tiny problem with this is that as long as you don't empty the event queue,
the select will return with isset even if it timed out while waiting
(dvb_frontend.c:dvb_frontend_poll).
