From a14d982962c1c3caee99ddeea632d97fc851ea60 Mon Sep 17 00:00:00 2001 From: Mark Brown Date: Thu, 18 Jul 2013 22:43:19 +0100 Subject: [PATCH] ASoC: sta32x: Use power efficient workqueue None of the delayed work the driver schedules has particularly short delays and it is not performance sensitive so let the scheduler run it wherever is most efficient rather than in a per CPU workqueue by using the system power efficient workqueue.
