Hence, the driver fails to probe the device if: - The device has already been enabled for wakeup (by e.g. sysfs) - The driver has been unloaded and is being loaded again. This goal of the patch is to fix the above cases. Overwhelming majority of the drivers do not check device_init_wakeup return code.
