Summary
platform/x86: lenovo-wmi-helpers: Fix memory leak in lwmi_dev_evaluate_int()
Details

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

platform/x86: lenovo-wmi-helpers: Fix memory leak in lwmidevevaluate_int()

lwmidevevaluate_int() leaks output.pointer when retval == NULL (found by sashiko.dev [1]).

Fix it by moving ret_obj = output.pointer' outside of theif (retval)' block so that it is always freed by the __free cleanup callback.

No functional change intended.
