If you, or anyone else, feels it should not be added to the stable tree, please let <stable@xxxxxxxxxxxxxxx> know about it. commit 679970dd06747de97471b6e134980d9867cde0f3 Author: Hans de Goede <hdegoede@xxxxxxxxxx> Date: Tue Dec 13 13:33:19 2022 +0100 ASoC: rt5670: Remove unbalanced pm_runtime_put() [ Upstream commit 6c900dcc3f7331a67ed29739d74524e428d137fb ] For some reason rt5670_i2c_probe() does a pm_runtime_put() at the end of a successful probe. But it has never done a pm_runtime_get() leading to the following error being logged into dmesg: rt5670 i2c-10EC5640:00: Runtime PM usage count underflow! Fix this by removing the unnecessary pm_runtime_put().
