740 // a kernel wake lock. However, once the last pending event has been read, the device
741 // driver will release the kernel wake lock. To prevent the system from going to sleep
742 // when this happens, the EventHub holds onto its own user wake lock while the client
750 mLock.unlock(); // release lock before poll, must be before release_wake_lock
