Summary
net: renesas: rswitch: avoid use-after-put for a device tree node
Details

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 rswitchdevice structure is used at several driver locations. So passing this node to ofnode_put() after the first use is wrong.

Move ofnodeput() for this node to exit paths.
