Next we add a new structre the struct snd_soc_compr_ops in the struct snd_soc_dai_link. This is to be used for machine driver to perform any operations required for setting up compressed audio streams next is the compressed data operations, they are added using struct snd_compr_ops in the struct snd_soc_platform_driver.
