[alsa-devel] [PATCH] ASoC: twl6040: Use power efficient workqueue

[Mark Brown]

From: Mark Brown <broonie at linaro.org>

The accessory detect debounce work 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.
