kfree(adev->irq.client[i].sources); +adev->irq.client[i].sources = NULL;
Set adev->irq.client[i].sources to NULL in amdgpu_irq_fini also can fix NULL ptr in amdgpu_irq_disable_all.. But I didn't check why amdgpu_device_fini was called twice. This patch looks good.

Problem: When unloading due to failure amdgpu_device_fini was called twice which was leading to NULL ptr in amdgpu_irq_disable_all. Fix: Call amdgpu_device_fini only once from amdgpu_driver_unload_kms.
