[PATCH 1/2] ACPI: SBS: Simplify the driver init code

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



acpi_bus_register_driver() will check acpi_disable and return
-ENODEV, so the acpi_disable check outside the
acpi_bus_register_driver() is duplicated, can be removed.

Also we can just return from acpi_bus_register_driver() then
we can simplify the code further.
