[PATCH v1 03/10] platform/x86: fujitsu-laptop: Stop setting acpi_device_name/class()

["Rafael J. Wysocki" <rafael@kernel.org>]

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

The driver sets acpi_device_name() that are only used for printing
messages and initializing input class device names.  Since
ACPI_FUJITSU_BL_DEVICE_NAME and ACPI_FUJITSU_LAPTOP_DEVICE_NAME can
be used directly in all of those cases, make the driver do so and
stop setting acpi_device_name() in it.

Likewise, acpi_device_class() set by the driver are never read
afterward, so make the driver stop setting it and drop the symbol
defined specifically for this purpose.

No intentional functional impact.
