[PATCH v1 08/10] platform/x86: toshiba_acpi: Do not use uninitialized device_class

[Rafael J. Wysocki]

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

The pnp.device_class string in the ACPI companion of the platform
device used for binding the driver is never initialized, so passing
it to acpi_bus_generate_netlink_event() is effectively equivalent to
passing an empty string literal to that function.

Accordingly, make the driver do the latter instead of doing the former.

No intentional functional impact.
