Wysocki The ACPI_HANDLE() macro is a wrapper arond the ACPI_COMPANION() macro and the ACPI handle produced by the former comes from the ACPI device object produced by the latter, so it is way more straightforward to evaluate the latter directly instead of passing the handle produced by the former to acpi_bus_get_device(). Modify ideapad_acpi_add() accordingly (no intentional functional impact). Signed-off-by: Rafael J.
