Title
drm/i915/gem: Fix NULL deref in I915_CONTEXT_PARAM_SSEU
Summary
In the Linux kernel, the following vulnerability has been resolved: drm/i915/gem: Fix NULL deref in I915_CONTEXT_PARAM_SSEU Setting context engine slot N into I915_ENGINE_CLASS_INVALID / I915_ENGINE_CLASS_INVALID_NONE and attempting to apply I915_CONTEXT_PARAM_SSEU to the same slot N will deref NULL. Fix that. Discovered using AI-assisted static analysis confirmed by Intel Product Security. (cherry picked from commit 36eda5b5c2d40da41cc0a5403c26986237cf9e87)
