I think no, these are plain numbers given in the form of BIT(x) - 1 to show the HW limit on the values (in bits). ... > > + intg_time = iio_gts_find_int_time_by_sel(&data->gts, intg_time_idx); > > + if (intg_time < 0) > > + delay = apds9306_repeat_rate_period[repeat_rate_idx]; > > 'delay' is always overwritten by the line below. Seems like entire conditional here is not needed as it's implied in the max(). And max() should take both signed or unsigned types, different types might have a side effect. > > + /* > > + * Whichever is greater - integration time period or > > + * sampling period. > > + */ > > + delay = max(intg_time, > > + apds9306_repeat_rate_period[repeat_rate_idx]); -- With Best Regards, Andy Shevchenko
