I can reproduce with your config (I guess that removing the driver for analog 
audio hides the issue)

I'm really feel like simple_util_clean_reference(card) in simple_probe() 
errors path should not be called anymore, since
https://lore.kernel.org/all/87zfk4o5l2.wl-kuninori.morimoto.gx@renesas.com/

I'm adding Kuninori Morimoto in the to list of this thread for extra input 
(See thread at https://lore.kernel.org/all/B8EF5196-55FB-44EC-B93C-E327C791225B@gmail.com/) as they made that change.
Especially those commits:
      ASoC: audio-graph-card2: use __free(device_node) for device node
      ASoC: audio-graph-card: use __free(device_node) for device node
      ASoC: simple-card: use __free(device_node) for device node
