Reference to the non-existing kconfig symbol SND_SOC_AC97_BUS_NEW

[Lukas Bulwahn]

Dear Robert,

In commit 1c8bc7b3de5e ("ASoC: pxa: switch to new ac97 bus support"),
you changed the select in config SND_PXA2XX_SOC_AC97 from
SND_SOC_AC97_BUS to the non-existing symbol SND_SOC_AC97_BUS_NEW.

Hence, since then, ./scripts/checkkconfigsymbols.py is reporting this
invalid reference:

  SND_SOC_AC97_BUS_NEW
  Referencing files: sound/soc/pxa/Kconfig

Robert, it seems that you were already informed in the past and
already acknowledged that some work is required to fix this in this
email response:
https://lore.kernel.org/all/878skf1zmp.fsf@xxxxxxxxxxxxxx/

As of next-20211117, this issue is still unaddressed, though. Are you
going to address this issue? Is this patch just pending somewhere?

Best regards,

Lukas
