When a plug event is detect report the full state of all status bits, don't assume that there will have been a previous unplug event to clear all the bits. Report the state of both HEADPHONE and MICROPHONE bits according to detected type, and clear all the button status bits. The current button status is already checked and reported at the end of the function. During a system suspend the jack could be unplugged and plugged, possibly changing the jack type. On resume the interrupt status will indicate a plug event - there will not be an unplug event to clear the bits.
