[ Upstream commit b8bee48e38f2ddbdba5e58bc54ef54bb7d8d341b ]

The build can fail with:

ERROR: modpost: "__auxiliary_driver_register"
[sound/usb/qcom/snd-usb-audio-qmi.ko] undefined!
ERROR: modpost: "auxiliary_driver_unregister"
[sound/usb/qcom/snd-usb-audio-qmi.ko] undefined!

Select AUXILIARY_BUS when SND_USB_AUDIO_QMI is enabled.
