From 2f35c630f7d49efdef29b58d81ed2531ddd916d9 Mon Sep 17 00:00:00 2001 From: Takashi Iwai Date: Fri, 27 Feb 2015 22:43:26 +0100 Subject: ALSA: hda - Use standard workqueue for unsol and jack events The events that are handled by HD-audio drivers are no frequent and urgent ones, so we can use the standard workqueue without any problem nowadays.
