From 57622aef86d21d459e937c72f578050ff4a91af5 Mon Sep 17 00:00:00 2001 From: Jiada Wang Date: Wed, 30 Sep 2015 13:54:13 +0900 Subject: [PATCH 1/2] ASoC: wm8962: balance pm_runtime_enable pm_runtime_enable is called in probe to enable runtime PM for wm8962 codec, but pm_runtime_disable isn't called in remove callback, nor is called in error path if probe fails after runtime PM is enabled, this causes unbalanced pm_runtime_enable. This patch Adds pm_runtime_disable in remove callback and error path, to balance pm_runtime_enable.
