+Subject: [PATCH 1442/4131] drm/amdkfd: Remove duplicate pqm_uninit()
+
+pqm_uninit() will be called in kfd_process_notifier_release(), which
+is when the process exits. Calling it in kfd_unbind_process_from_device()
+is duplicate and in fact incorrect, because pqm should not be
+uninitalized as long as the process still exists.
