From d3a177c71852d2eac42c74a6b2cb7af242061d21 Mon Sep 17 00:00:00 2001 From: Mark Brown Date: Fri, 19 Jul 2013 18:47:34 +0100 Subject: extcon: gpio: Use power efficient workqueue for debounce 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.
