PM: sleep: Integrate suspend-to-idle with generig suspend flow
After previous changes the suspend-to-idle code flow can be integrated more tightly with the generic system suspend code flow by making suspend_enter() call s2idle_loop() later and removing the direct invocations of dpm_noirq_begin(), dpm_noirq_suspend_devices(), dpm_noirq_end(), and dpm_noirq_resume_devices() from the latter, so do that. This change is not expected to alter functionality. Signed-off-by: Rafael J. Wysocki <rafael.j.wysocki@intel.com> Acked-by: Thomas Gleixner <tglx@linutronix.de>
