This is a note to let you know that I've just added the patch titled crypto: omap-sham - Use pm_runtime_resume_and_get() in omap_sham_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: crypto-omap-sham-use-pm_runtime_resume_and_get-in-om.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 ffced4815d873931690a41403f70912ad15dabfe Author: Shang XiaoJing <shangxiaojing@xxxxxxxxxx> Date: Thu Nov 24 14:49:40 2022 +0800 crypto: omap-sham - Use pm_runtime_resume_and_get() in omap_sham_probe() [ Upstream commit 7bcceb4c9896b1b672b636ae70fe75110d6bf1ad ] omap_sham_probe() calls pm_runtime_get_sync() and calls pm_runtime_put_sync() latter to put usage_counter. However, pm_runtime_get_sync() will increment usage_counter even it failed. Fix it by replacing it with pm_runtime_resume_and_get() to keep usage counter balanced.
