From aeaccef0bc0d364792ecc9455cb13d007fd7a371 Mon Sep 17 00:00:00 2001 From: Ramesh Babu Date: Wed, 17 Feb 2016 21:34:01 +0530 Subject: [PATCH] ASoC: hdac_hdmi: Fix to keep codec power active during enumeration. The codec power is turned OFF in the first explicit call to pm_runtime_suspend to keep the i915 refcount balanced. During regular operation, the power is turned ON/OFF in runtime PM handlers.
