Wysocki Replace the ACPI_DEBUG_PRINT() instances in thermal.c with acpi_handle_debug() calls and modify the ACPI_THERMAL_TRIPS_EXCEPTION() macro in there to use acpi_handle_info() internally, which among other things causes the excessive log level of the messages printed by it to be increased. Drop the _COMPONENT and ACPI_MODULE_NAME() definitions that are not used any more from thermal.c, drop the no longer needed ACPI_THERMAL_COMPONENT definition from the headers and update the documentation accordingly. While at it, add a pr_fmt() definition to thermal.c, drop the PREFIX definition from there and replace some pr_warn() calls with pr_info() or acpi_handle_info() to reduce the excessive log level and (in the latter case) facilitate easier identification of the message source.
