Subject: [PATCH] regulator: core: Use the power efficient workqueue for delayed powerdown
Date: Thu, 18 Jul 2013 11:53:51 +0100 [thread overview]
Message-ID: <1374144831-25622-1-git-send-email-broonie@kernel.org> (raw)
From: Mark Brown <broonie@linaro.org>
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.
