Re: [alsa-devel] [PATCH] ASoC: soc-core: call soc_cleanup_card_debugfs() from snd_soc_unregister_card()

Hi Takashi

...

snd_soc_register_card() <-> snd_soc_unregister_card()

• soc_init_card_debugfs() ????
• snd_soc_instantiate_card() <-> - soc_cleanup_card_resources()
  • soc_bind_dai_link() - soc_remove_dai_links()
  • soc_probe_aux_dev() - soc_remove_aux_dev()
  • card->probe() - card->remove()
  • ???? - soc_cleanup_card_debugfs()

IMO, a better change would be to call soc_init_card_debugfs() in snd_soc_instantiate_card(), supposing that the debugfs is available only for instantiated objects. This will fix the messy leakage at error paths, too.

OK, here we go.

My concern is that my next patch will "return ret" if snd_soc_instantiate_card() was failed, but is it OK ?
