From b8629411bf2c0979ae130511f27fd708e2fd102e Mon Sep 17 00:00:00 2001 From: Krzysztof Kozlowski Date: Wed, 9 Apr 2014 15:20:13 +0200 Subject: extcon: max77693: 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.
