From eb399d3c99d8b411bfc46e67ea329ddc1ca64e87 Mon Sep 17 00:00:00 2001 From: Takashi Iwai Date: Fri, 27 Nov 2015 14:53:35 +0100 Subject: [PATCH] ALSA: hda - Skip ELD notification during PM process The ELD notification can be received asynchronously from the graphics side, and this may happen just at the moment the sound driver is processing the suspend or the resume, and it would confuse the whole procedure. Since the ELD and connection states are updated in anyway at the end of the resume, we can skip it when received during PM process.
