[PATCH 07/10] platform/x86: fujitsu-laptop: simplify acpi_bus_register_driver() error handling

[MichaÅ KÄpieÅ]

From: Alan Jenkins <alan-jenkins@xxxxxxxxxxxxxx>

A separate variable is not needed to handle error codes returned by
acpi_bus_register_driver().  If the latter fails, just use the value it
returned as the value returned by fujitsu_init().
