This is a note to let you know that I've just added the patch titled ASoC: mediatek: mt8192:Fix Unbalanced pm_runtime_enable in mt8192_afe_pcm_dev_probe to the 5.14-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-mediatek-mt8192-fix-unbalanced-pm_runtime_enabl.patch and it can be found in the queue-5.14 subdirectory. If you, or anyone else, feels it should not be added to the stable tree, please let <stable@xxxxxxxxxxxxxxx> know about it. commit 70437642a2b61b1fee2b4b19f7d961997f2c8f12 Author: Zhang Qilong <zhangqilong3@xxxxxxxxxx> Date: Fri Jun 18 22:11:03 2021 +0800 ASoC: mediatek: mt8192:Fix Unbalanced pm_runtime_enable in mt8192_afe_pcm_dev_probe [ Upstream commit 2af2f861edd21c1456ef7dbec52122ce1b581568 ] Add missing pm_runtime_disable() when probe error out. It could avoid pm_runtime implementation complains when removing and probing again the driver.
