#     
#     Pull ACPI fixes from Rafael Wysocki:
#      "These fix a memory management regression in ACPICA, repair an ACPI
#       blacklist entry damaged inadvertently during the 5.11 cycle and fix
#       the bookkeeping of devices with the same primary device ID in the ACPI
#       core.
#     
#       Specifics:
#     
#        - Make ACPICA use the same object cache consistently when allocating
#          and freeing objects (Vegard Nossum)
#     
#        - Add a callback pointer removed inadvertently during the 5.11 cycle
#          to the ACPI backlight blacklist entry for Sony VPCEH3U1E (Chris
#          Chiu)
#     
#        - Make the ACPI device enumeration core use IDA for creating names of
#          ACPI device objects with the same primary device ID to avoid using
#          duplicate device object names in some cases (Andy Shevchenko)"
#     
#     * tag 'acpi-5.12-rc5' of git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm:
#       ACPICA: Always create namespace nodes using acpi_ns_create_node()
#       ACPI: scan: Use unique number for instance_no
#       ACPI: video: Add missing callback back for Sony VPCEH3U1E
