This is a note to let you know that I've just added the patch titled cpufreq: powernow-k8: Use related_cpus instead of cpus in driver.exit() 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: cpufreq-powernow-k8-use-related_cpus-instead-of-cpus.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 7d2539efe66ea798f6ffa79eac7ee4341372656f Author: Liao Chang <liaochang1@xxxxxxxxxx> Date: Sat Aug 26 09:51:13 2023 +0000 cpufreq: powernow-k8: Use related_cpus instead of cpus in driver.exit() [ Upstream commit 03997da042dac73c69e60d91942c727c76828b65 ] Since the 'cpus' field of policy structure will become empty in the cpufreq core API, it is better to use 'related_cpus' in the exit() callback of driver.
