From 1f4956fd96c98e3fbe9a2818014cf36854398db0 Mon Sep 17 00:00:00 2001 From: Jeeja KP Date: Fri, 18 Dec 2015 15:12:06 +0530 Subject: [PATCH] ASoC: Intel: Skylake: enable interrupt as wake source in active suspend In active suspend, any HDA interrupt should wake the system. When device enters active suspend, we need to enable HDA controller interrupt as wake source. Similarly disable HDA controller interrupt as wake source when exiting active suspend.
