Description

In the Linux kernel, the following vulnerability has been resolved: usb: musb: omap2430: Fix use-after-free in omap2430_probe() In omap2430_probe(), of_node_put(np) is called prematurely before the last access to np, leading to a use-after-free if the node's reference count drops to zero. Move the of_node_put() calls after the last use of np in both the success and error paths.
