This is a note to let you know that I've just added the patch titled ASoC: rockchip: spdif: Add missing clk_disable_unprepare() in rk_spdif_runtime_resume() to the 5.4-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-rockchip-spdif-add-missing-clk_disable_unprepar.patch and it can be found in the queue-5.4 subdirectory. If you, or anyone else, feels it should not be added to the stable tree, please let <stable@xxxxxxxxxxxxxxx> know about it. commit a9f09861f94f0719964eda0568a32b6e72cef43b Author: Wang Jingjin <wangjingjin1@xxxxxxxxxx> Date: Thu Dec 8 14:39:00 2022 +0800 ASoC: rockchip: spdif: Add missing clk_disable_unprepare() in rk_spdif_runtime_resume() [ Upstream commit 6d94d0090527b1763872275a7ccd44df7219b31e ] rk_spdif_runtime_resume() may have called clk_prepare_enable() before return from failed branches, add missing clk_disable_unprepare() in this case.
