Subject: ASoC: wm8962: Use power efficient workqueue
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=da72c9619f4df033d431a0a4cee715cf14c78433;p=linux-beck.git

ASoC: wm8962: Use power efficient workqueue

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.
