This is a note to let you know that I've just added the patch titled ASoC: rk817: Use devm_clk_get() in rk817_platform_probe to the 5.15-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-rk817-use-devm_clk_get-in-rk817_platform_probe.patch and it can be found in the queue-5.15 subdirectory. If you, or anyone else, feels it should not be added to the stable tree, please let <stable@xxxxxxxxxxxxxxx> know about it. commit 7fcf5d81fafe2ae8b98d863a430a9d7e751de509 Author: Miaoqian Lin <linmq006@xxxxxxxxx> Date: Mon Apr 4 09:07:46 2022 +0000 ASoC: rk817: Use devm_clk_get() in rk817_platform_probe [ Upstream commit 8ba08d3a367a70f707b7c5d53ad92b98b960ee88 ] We need to call clk_put() to undo clk_get() in the error path. Use devm_clk_get() to obtain a reference to the clock, It has the benefit that clk_put() is no longer required.
