reverse is used in resume. Android pre-defines three levels: enum {EARLY_SUSPEND_LEVEL_BLANK_SCREEN = 50,EARLY_SUSPEND_LEVEL_STOP_DRAWING = 100,EARLY_SUSPEND_LEVEL_DISABLE_FB = 150,}; If you want your device to perform its early suspend callback before the FB device is disabled, the device driver should set the level value to a value smaller than 150, then register the early_suspend structure with the system. The registration and anti-registratio
