From eb4d5fc1f0ce89e3d5b072c594a1e213a0e05881 Mon Sep 17 00:00:00 2001 From: Mark Brown Date: Thu, 27 Sep 2012 18:35:24 +0100 Subject: [PATCH] ASoC: wm_hubs: Ensure volume updates are handled during class W startup In some circumstances we may need to flush volume updates to the device after switching to class W mode. Do this unconditionally to ensure that these situations are handled.
