From: Michał Kępień <kernel@...pniu.pl>
To: Jonathan Woithe <jwoithe@...t42.net>,

Andy Shevchenko <andy@...radead.org>
Cc: platform-driver-x86@...r.kernel.org, linux-kernel@...r.kernel.org
Subject: [PATCH v2 7/7] platform/x86: fujitsu-laptop: Clean up constants
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.
