From aac80fa7240ae13be02fcebc271f5c557f08409e Mon Sep 17 00:00:00 2001 From: Mark Brown Date: Thu, 18 Jul 2013 11:52:04 +0100 Subject: [PATCH] regulator: core: Use the power efficient workqueue for delayed powerdown There is no need to use a normal per-CPU workqueue for delayed power downs as they're not timing or performance critical and waking up a core for them would defeat some of the point.
