[PATCH] drm/amdgpu/acp: Make PM domain really work
Devices created by mfd_add_hotplug_devices() don't really increase the index of its name, so get_mfd_cell_dev() cannot find any device, hence a NULL dev is passed to pm_genpd_add_device(): [ 56.974926] (NULL device *): amdgpu: device acp_audio_dma.0.auto added to pm domain [ 56.974933] (NULL device *): amdgpu: Failed to add dev to genpd [ 56.974941] [drm:amdgpu_device_ip_init [amdgpu]] *ERROR* hw_init of IP block failed -22 [ 56.975810] amdgpu :00:01.0: amdgpu: amdgpu_device_ip_init failed [ 56.975839] amdgpu :00:01.0: amdgpu: Fatal error during GPU init [ 56.977136] [ cut here ] [ 56.977143] kernel BUG at mm/slub.c:4206!
