Description

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

media: v4l2-core: Fix a potential resource leak in v4l2_fwnode_parse_link()

If fwnode_graph_get_remote_endpoint() fails, 'fwnode' is known to be NULL,
so fwnode_handle_put() is a no-op.

Release the reference taken from a previous fwnode_graph_get_port_parent()
call instead.

Also handle fwnode_graph_get_port_parent() failures.

In order to fix these issues, add an error handling path to the function
and the needed gotos.
