Wysocki" Date: Tue, 17 Oct 2023 22:05:23 +0200 Subject: thermal: ACPI: Move the ACPI thermal library to drivers/acpi/ The ACPI thermal library contains functions that can be used to retrieve trip point temperature values through the platform firmware for various types of trip points. Each of these functions basically evaluates a specific ACPI object, checks if the value produced by it is reasonable and returns it (or THERMAL_TEMP_INVALID if anything fails). It made sense to hold it in drivers/thermal/ so long as it was only used by the code in that directory, but since it is also going to be used by the ACPI thermal driver located in drivers/acpi/, move it to the latter in order to keep the code related to evaluating ACPI objects defined in the specification proper together. No intentional functional impact. Signed-off-by: Rafael J.
