Subject: [PATCH] drm/xe: Disable garbage collector work item on SVM close
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

When an SVM is closed, the garbage collector work item must be stopped
synchronously and any future queuing must be prevented. Replace
flush_work() with disable_work_sync() to ensure both conditions are
met.
