I do not believe that this is correct. The fact that _some_ driver
failed to attach to a device does not necessarily mean that device
itself does not exist. While this assuption might work for platform
devices it won't work for other busses.
As fasr as ALSA goes, if they want to abort loading module if device
is not present they will have to separate device probing from final
driver binding.
