You may get further e-mails resulting from automated or manual testing and review of the tree, please engage with people reporting problems and send followup patches addressing any issues that are reported if needed. If any updates are required or you are submitting further changes they should be sent as incremental updates against current git, existing patches will not be replaced. Please add any relevant lists and maintainers to the CCs when replying to this mail. Thanks, Mark From 57622aef86d21d459e937c72f578050ff4a91af5 Mon Sep 17 00:00:00 2001 From: Jiada Wang Date: Wed, 30 Sep 2015 13:54:13 +0900 Subject: [PATCH] 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.
