The reply was based on the fact that looking at 
'snd_soc_unregister_component' that's a macro for 
'snd_soc_unregister_component_by_driver'. The latter cycles through all 
registered components and if nothing is found related to the given dev, 
then it results in a no-op.
So calling 'snd_soc_unregister_component' on a failed 
'snd_soc_register_component' looked harmless to me.

What did I miss?
