[PATCH] Platform / x86: Make fujitsu_laptop use acpi_bus_update_power()

Use the new function acpi_bus_update_power(), which is safer than
acpi_bus_get_power(), for getting device power state in
acpi_fujitsu_add().

Hi Len,

This patch should go after [11/13] in the "ACPI / PM: Rework power resources
management" series. I hope Matthew won't mind if it goes in through your tree.

Thanks,
Rafael
