Description
In the Linux kernel, the following vulnerability has been resolved: power: supply: rk817: Fix node refcount leak Dan Carpenter reports that the Smatch static checker warning has found that there is another refcount leak in the probe function. While of_node_put() was added in one of the return paths, it should in fact be added for ALL return paths that return an error and at driver removal time.
