[PATCH 1/4] platform/x86: fujitsu-laptop: simplify acpi_bus_register_driver() error handling
From: MichaÅ KÄpieÅ
Date: Fri Jan 13 2017 - 06:03:07 EST
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().
