Summary
device property: fix of node refcount leak in fwnode_graph_get_next_endpoint()
Details

In the Linux kernel, the following vulnerability has been resolved:

device property: fix of node refcount leak in fwnodegraphgetnextendpoint()

The 'parent' returned by fwnodegraphgetportparent() with refcount incremented when 'prev' is not NULL, it needs be put when finish using it.

Because the parent is const, introduce a new variable to store the returned fwnode, then put it before returning from fwnodegraphgetnextendpoint().
