timed_gpio.c uses hrtimer to switch off the gpio. However, hrtimer does not get fired after the CPU suspends. Hence, if the CPU suspends before the timer gets fired, the gpio stays on until the next time when CPU wakes up causing unnecessary battery drain (which can be as long as 15 minutes). IMHO, we should replace hrtimer by android alarm timer to make sure that CPU wakes up at the right time and gpio gets turned off.
