From def656fe22abb4fbf174a982dcef1d40274ddb11 Mon Sep 17 00:00:00 2001 From: Jeeja KP Date: Fri, 9 Oct 2015 09:01:49 +0100 Subject: [PATCH] ASoC: Intel: Skylake: Verify the status bit before handling interrupt Like we have in legacy mode HDA driver, we need to check the status bit and handle interrupt only when it is not zero or all bits set. We typically see the status as all 1's when controller resumes from suspend, So add the check here as well and don't handle for these cases.
