Well, the tda1997x_irq_sus() does this:

if (debug)
tda1997x_detect_std(state, NULL);

Perhaps there is a better way, but I think I will leave it for now.
Also there is the issue of ignoring tda1997x_detect_std() return value,
but I can now see it's only a case in tda1997x_query_dv_timings(), easy
to fix.

Will post an update shortly.

Thanks for your comments,
