Re: [alsa-devel] [PATCH] ASoC: core: move DAI pre-links initiation to snd_soc_instantiate_card

...

probe_end:

•   if (ret < 0)
  

•   if (ret < 0 && ret != -EPROBE_DEFER)
            soc_cleanup_card_resources(card);
  

Should not call soc_cleanup_card_resources() if soc_init_dai_link() returns fail. Some context has not initialized yet in the case.

Why not? You need to clean up the platform naming if links fails which will causes a use-after-free bug if you don't clean it up.
