Currently CODEC and platform drivers have their module reference count incremented soc_probe_dai_link() whilst CPU DAI drivers have their reference count incremented in soc_bind_dai_link().
CPU DAIs should have their reference count incremented in soc_probe_dai_link() just like the CODEC and platform drivers.
