Description
In the Linux kernel, the following vulnerability has been resolved:
usb: typec: wusb3801: fix fwnode refcount leak in wusb3801_probe()
I got the following report while doing fault injection test:
OF: ERROR: memory leak, expected refcount 1 instead of 4,
of_node_get()/of_node_put() unbalanced - destroy cset entry:
attach overlay node /i2c/tcpc@60/connector
If wusb3801_hw_init() fails, fwnode_handle_put() needs be called to
avoid refcount leak.
