It does NOT prove the drivers bind on a booted board, and does NOT exercise CONFIG_SND_SOC_CANAAN_K230_AUDIO/_INNO or CONFIG_SND_SOC_K230_INNO through a real Kconfig/oldconfig pass -- that requires the full nix build this task was told not to run. See docs/research/mainline-audio-port.md for the remaining DMA blocker that stops the card from completing probe even after a full build."
