[PATCH v1 04/10] platform/x86: fujitsu-tablet: 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_class() which is never read afterward,
so make it stop doing that and drop the symbol defined specifically
for this purpose.

For consistency, also make it stop setting acpi_device_name() and add
a name field to the "fujitsu" structure for storing the name string
used during input class device initialization.

While at it, use scnprintf() instead of snprintf() for populating the
name and phys fields of the "fujitsu" structure.

No intentional functional impact.
