device property: Make fwnode_handle_get() return the fwnode
The fwnode_handle_get() function is used to obtain a reference to an fwnode. A common usage pattern for the OF equivalent of the function is: mynode = of_node_get(node); Similarly make fwnode_handle_get() return the fwnode to which the reference was obtained.
