Do not fail probing when device_init_wakeup fails.
device_init_wakeup fails when the device is already enabled as wakeup
device. Hence, the driver fails to probe the device if:
- The device has already been enabled for wakeup (via 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 value.
