#     Pull ACPI fixes from Rafael Wysocki:
#      "Fix possible use-after-free in the ACPI CPPC support code (John Garry)
#       and prevent the ACPI HMAT parsing code from using possibly incorrect
#       data coming from the platform firmware (Daniel Black)"

#     * tag 'acpi-5.4-rc4' of git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm:
#       ACPI: CPPC: Set pcc_data[pcc_ss_id] to NULL in acpi_cppc_processor_exit()
#       ACPI: HMAT: ACPI_HMAT_MEMORY_PD_VALID is deprecated since ACPI-6.3
