We should tear down the client source that allocated by the
SOC15_IH_CLIENTID_VMC (the last one) if it (the second one) gets failed.
There is no such thing as a teardown. amdgpu_irq_add_id() registers the
irq callback for the clientid/srcid combination, but there isn't an
unregister function.
Christian.
Thanks,
