... split it to an individual module, i.e.:
snd-soc-usb-objs := soc-usb.o

Otherwise it'll lead to a hard-dependency to snd-soc-core on
snd-usb-audio, which is utterly unnecessary for most of other
devices.
Got it...getting this to compile as its own separate module also
required some changes to the other layers I had. Anyway, I've reworked
some of the dependencies with other drivers and is working fine now.
Thanks
