Since commit 1a50d9403fb9 ("treewide: Fix probing of devices in DT
overlays"), the FWNODE_FLAG_NOT_DEVICE is set on nodes present in the
overlay. Having this flag set leads to some wrong devlink links.
For instance, some links can be created with a supplier set to a parent
device instead of the device itself.
This series clears the FWNODE_FLAG_NOT_DEVICE in some specific location
to fix the wrong links issues.
- device_add()
When a device is added, the related fwnode (if any) is populated as
a struct device. It makes sense to clear the flag at that point and so
avoid differences between DT used with or without overlays.
- of_link_phandle()
If the supplier device has a compatible string and 'is available', a
device is going to be created soon to handle this node. In that case,
to avoid a link created using the supplier parent device instead of
the device itself, clearing the FWNODE_FLAG_NOT_DEVICE makes sense.
