Looks like unnecessary white space change to me.

  void kgd2kfd_device_exit(struct kfd_dev *kfd)
  {
      if (kfd->init_complete) {
-        kgd2kfd_suspend(kfd, false);

Where is the call to this function now?

Christian.

In patch 'drm/amdgpu: Add early fini callback' in
amdgpu_device_ip_fini_early->amdgpu_amdkfd_suspend->kgd2kfd_suspend

Andrey


          device_queue_manager_uninit(kfd->dqm);
          kfd_interrupt_exit(kfd);
          kfd_topology_remove_device(kfd);
