Venturing deeper into the bikesheeding territory but I'd leave the variable declarations be and move init of adev before the check. Matter of preference but calling something that needs to be error checked in variable init breaks the usual ret = func(some, arguments); if (ret) goto explosions; flow. > - if (acpi_bus_get_device(handle, &adev)) > + if (!adev) > goto out;
