Description
In the Linux kernel, the following vulnerability has been resolved:
media: v4l2-fwnode: Fix fwnode leak in v4l2_fwnode_parse_link
In v4l2_fwnode_parse_link(), the remote endpoint fwnode reference is
acquired using fwnode_graph_get_remote_endpoint(). This reference is
properly released in the error paths, but it is leaked on the success
path.
Add the missing fwnode_handle_put() before returning 0 to prevent the
reference leak.
[Sakari Ailus: Fix subject prefix and coding style a little.]
