Change the suspend/resume callback to suspend_noirq/resume_noirq callback to make sure keypad interrupts are enabled during suspend, as when there is keypad interrupt coming after suspend callback is called, the interrupt handler will still be called and it will disable keypad interrupts, it will cause keypad can NOT generate interrupts to wake up system from suspend.
