[ Upstream commitdd9f9cc1e6] On init we have sequence: for_each_card_prelinks(card, i, dai_link) { ret = snd_soc_add_pcm_runtime(card, dai_link); ret = init_some_other_things(...); if (ret) goto probe_end: for_each_card_rtds(card, rtd) { ret = soc_init_pcm_runtime(card, rtd); probe_end: while on exit: for_each_card_rtds(card, rtd) snd_soc_link_exit(rtd); If init_some_other_things() step fails due to error we end up with not fully setup rtds and try to call snd_soc_link_exit on them, which depending on contents on .link_exit handler, can end up dereferencing NULL pointer.
