From 351d0015c1bf5977b9aa88c325d8ff56158f762e Mon Sep 17 00:00:00 2001 From: Zhang Qilong Date: Wed, 11 Nov 2020 12:13:24 +0800 Subject: [PATCH] ASoC: wm8994: Fix PM disable depth imbalance on error [ Upstream commit b8161cbe55a1892a19a318eaebbda92438fa708c ] The pm_runtime_enable will increase power disable depth. Thus a pairing decrement is needed on the error handling path to keep it balanced according to context.
