In the Linux kernel, the following vulnerability has been resolved:
usb: typec: tcpci: fix of node refcount leak in tcpci_register_port()
I got the following report while doing device(mt6370-tcpc) load
test with CONFIG_OF_UNITTEST and CONFIG_OF_DYNAMIC enabled:
OF: ERROR: memory leak, expected refcount 1 instead of 2,
of_node_get()/of_node_put() unbalanced - destroy cset entry:
attach overlay node /i2c/pmic@34/tcpc/connector
The 'fwnode' set in tcpci_parse_config() which is called
in tcpci_register_port(), its node refcount is increased
in device_get_named_child_node(). It needs be put while
exiting, so call fwnode_handle_put() in the error path of
tcpci_register_port() and in tcpci_unregister_port() to
avoid leak.
