A fix is available — apply it.

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

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

When vc4_save_hang_state() encounters an early return condition, it returns without freeing the previously allocated kernel_state, leaking memory.

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