From: Alan Jenkins Date: Wed, 8 Feb 2017 13:46:30 +0000 (+0100) Subject: platform/x86: fujitsu-laptop: simplify acpi_bus_register_driver() error handling X-Git-Tag: v4.11-rc3~34^2~4 X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=c1d1e8a051761fb808308dab32b9351e1d1fbb9b;p=karo-tx-linux.git platform/x86: fujitsu-laptop: simplify acpi_bus_register_driver() error handling 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().
