Subject: [PATCH 0/2] change to use ACPI_FREE() to free the ACPI memory

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().

Wang ShaoBo (2):
ACPI: pfr_telemetry: use ACPI_FREE() to free acpi_object
ACPI: pfr_update: use ACPI_FREE() to free acpi_object
