[PATCH] fix: drm/i915: __live_active_setup: kfree bypasses kref_put in early error path

[WenTao Liang]

When heap_fence_create fails, the early error path calls kfree(active)
  directly instead of __live_put(active), bypassing the kref_put path that
  would call i915_active_fini for proper resource teardown. This skips
  cleanup of the i915_active state while the initial kref from kref_init
  remains unbalanced.
