4.9-stable review patch. If anyone has any objections, please let me know.
------------------
From: Frank Praznik frank.praznik@gmail.com
commit 765a1077c85e5f2efcc43582f80caf43a052e903 upstream.
The LED subsystem provides the LED_CORE_SUSPENDRESUME flag to handle automatically turning off and restoring the state of device LEDs during suspend/resume. Use this flag instead of saving and restoring the state locally.
