commit 4a7f4110f79163fd53ea65438041994ed615e3af upstream.
For each endpoint it encounters, fwnode_graph_devcon_match() checks whether the endpoint's remote port parent device is available. If it is not, it ignores the endpoint but does not put the reference to the remote endpoint port parent fwnode. For available devices the fwnode handle reference is put as expected.
Put the reference for unavailable devices now.
