Subject: [PATCH v1 1/5] ACPI: AC: Clean up printing messages

From: Rafael J. Wysocki <rafael.j.wysocki@...el.com>

Replace the ACPI_DEBUG_PRINT() and ACPI_EXCEPTION() instances
in ac.c with acpi_handle_debug() and acpi_handle_info() calls,
respectively, drop the _COMPONENT and ACPI_MODULE_NAME() definitions
that are not used any more, drop the no longer needed ACPI_AC_COMPONENT
definition from the headers and update the documentation accordingly.
