From bf9509e032076dc5850598814c243c45a8b81690 Mon Sep 17 00:00:00 2001 From: Krzysztof Kozlowski Date: Wed, 9 Apr 2014 15:20:15 +0200 Subject: [PATCH] extcon: max8997: Use power efficient workqueue for delayed cable detection Schedule delayed cable detection work on power efficient workqueue so the scheduler won't wake up idle core for that work. This extends the idle time for CPU cores and conserves power.
