From 819cddae7cfa9b7673c24c338199274ba175e2b3 Mon Sep 17 00:00:00 2001 From: Michał Kępień Date: Tue, 20 Feb 2018 06:24:54 +0100 Subject: platform/x86: fujitsu-laptop: Clean up constants MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Align all constant values defined in the module to a common indentation. Rename ACPI_FUJITSU_NOTIFY_CODE1 to ACPI_FUJITSU_NOTIFY_CODE as there is only one ACPI notification code used throughout the driver. Define all bitmasks using the BIT() macro. Clean up comments.
