## Overview

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

drm/i915/gem: Do not leak siblings[] on proto context error

After a successful BALANCE/PARALLEL_SUBMIT extension on context
creation, error during processing of next user extension leaks
the siblings[] array. Fix that.

Discovered using AI-assisted static analysis confirmed by
Intel Product Security.

(cherry picked from commit aa65e0a4b51b3b54b53e4142aaa2d997aa1061ff)
