Wysocki Notice that intel_button_array_enable() never disables the power button which is the only one needed to wake up the system from suspend-to-idle, so it can be safely called during suspend-to-idle as well as during "regular" system suspend, and rearrange the code in the driver's "suspend" and "resume" callbacks accordingly. While at it, use pm_suspend_no_platform() to check if the current suspend-resume cycle is suspend-to-idle, as that is the only case when the device should be enabled while suspended.
