This is a note to let you know that I've just added the patch titled ACPI: pfr_update: use ACPI_FREE() to free acpi_object to the 6.1-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: acpi-pfr_update-use-acpi_free-to-free-acpi_object.patch and it can be found in the queue-6.1 subdirectory. If you, or anyone else, feels it should not be added to the stable tree, please let <stable@xxxxxxxxxxxxxxx> know about it. commit dc8622ec0a3de8fe1dc02018bc5d8def5ec9678c Author: Wang ShaoBo <bobo.shaobowang@xxxxxxxxxx> Date: Fri Nov 18 14:32:19 2022 +0800 ACPI: pfr_update: use ACPI_FREE() to free acpi_object [ Upstream commit e335beed78ec82656dcb554f9fe560709f0dc408 ] acpi_evaluate_dsm_typed()/acpi_evaluate_dsm() should be coupled with ACPI_FREE() to free the ACPI memory, because we need to track the allocation of acpi_object when ACPI_DBG_TRACK_ALLOCATIONS enabled, so use ACPI_FREE() instead of kfree().
