Dear All：
1 I found some placeuse two !!, what's means
if(button-gpio != INVALID_GPIO)
state = !!((gpio_get_value(button-gpio) ? 1 : 0) ^ button-active_low);
else
state = !!button-adc_state;
2 is there some MSN group to study linux kernel or discuss it ?
Thanks and
!! is generally used to make the return bool value.
You can use kernelnewbies and linux kernel mailing list.
