Wysocki Notice that the enabled flag is only needed for active trip points, so drop struct acpi_thermal_state_flags, add a simple "bool valid" field to the definitions of all trip point structures instead of flags and add a "bool enabled" field to struct acpi_thermal_active. Adjust the code using the modified structures accordingly. No intentional functional impact. Signed-off-by: Rafael J.
