Description
In the Linux kernel, the following vulnerability has been resolved: regulator: core: fix unbalanced of node refcount in regulator_dev_lookup() I got the the following report: 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@62/regulators/exten In of_get_regulator(), the node is returned from of_parse_phandle() with refcount incremented, after using it, of_node_put() need be called.
