Subject: [PATCH 1/2] extcon: gpio: Use power efficient workqueue for debounce
Date: Fri, 19 Jul 2013 18:47:34 +0100	[thread overview]
Message-ID: <1374256055-26894-1-git-send-email-broonie@kernel.org> (raw)

From: Mark Brown <broonie@linaro.org>

The debounce timeout is generally quite long and the work not performance
critical so allow the scheduler to run the work anywhere rather than in
the normal per-CPU workqueue.
