This is a note to let you know that I've just added the patch titled ASoC: stm32: dfsdm: Fix PM disable depth imbalance in stm32_adfsdm_probe to the 5.19-stable tree which can be found at: http://www.kernel.org/git/?p=linux/kernel/git/stable/stable-queue.git;a=summary The filename of the patch is: asoc-stm32-dfsdm-fix-pm-disable-depth-imbalance-in-s.patch and it can be found in the queue-5.19 subdirectory. If you, or anyone else, feels it should not be added to the stable tree, please let <stable@xxxxxxxxxxxxxxx> know about it. commit b29ae9f8517c860622e36d90004363f2e1217505 Author: Zhang Qilong <zhangqilong3@xxxxxxxxxx> Date: Tue Sep 27 22:26:00 2022 +0800 ASoC: stm32: dfsdm: Fix PM disable depth imbalance in stm32_adfsdm_probe [ Upstream commit b9a0da5b2edcae2a901b85c8cc42efc5bec4bd7b ] 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. We fix it by moving pm_runtime_enable to the endding of stm32_adfsdm_probe.
