In debugfs cleanup patch: [PATCH 07/14] ASoC: Intel: Skylake: Add function to cleanup debugfs interface
you define skl_debugfs_exit separately - its usage is split and present in this very patch instead. However, for tplg counterpart - skl_tplg_exit - you've decided to combine both together. Why not separate tplg cleanup too?
