Description SMASH SMASH 2024-03-05 09:25:20 UTC 
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.
