In the Linux kernel, the following vulnerability has been resolved:

drm/vc4: Fix a memory leak in hang state error path

When vc4savehangstate() encounters an early return condition, it returns without freeing the previously allocated kernelstate, leaking memory.

Add the missing kfree() calls by consolidating the early return paths into a single place.
