skl_set_base_module_format() is called from a variety of places, so am I correct in stating that S24_LE never worked with this driver? If so, the patch should really be titled "ASoC: Intel: Skylake: enable S24_LE format support"

Also your commit message is confusing in the last sentence. What do you mean by "Setting sample_type to " when you only use what's provided by the topology?
