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
