Description
In the Linux kernel, the following vulnerability has been resolved: net: renesas: rswitch: avoid use-after-put for a device tree node The device tree node saved in the rswitch_device structure is used at several driver locations. So passing this node to of_node_put() after the first use is wrong. Move of_node_put() for this node to exit paths.
