[alsa-devel] [PATCH 2/4] ASoC: wm8753: Use power efficient workqueue

[Mark Brown]

From: Mark Brown <broonie at linaro.org>

The work used to allow the capcitors to ramp 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.
