The code to handle the SMART_SUSPEND driver PM flag is hard to follow and somewhat inconsistent with respect to devices without middle-layer (subsystem) callbacks. Namely, for those devices the core takes the role of a middle layer in providing the expected ordering of execution of callbacks (under the assumption that the drivers setting SMART_SUSPEND can reuse their PM-runtime callbacks directly for system-wide suspend). To that end, it prevents driver ->suspend_late and ->suspend_noirq callbacks from being executed for devices that are still runtime-suspended in __device_suspend_late(), because running the same callback funtion that was previously run by PM-runtime for them may be invalid. However, it does that only for devices without any middle-layer callbacks for the late/noirq/early suspend/resume phases even though it would be simpler and more consistent to skip the driver-lavel callbacks for all devices with SMART_SUSPEND set that are runtime-suspended in __device_suspend_late(). Simplify the code in accordance with the above observation. Suggested-by: Alan Stern <stern@rowland.harvard.edu> Signed-off-by: Rafael J.
