Ok, that should be fine. Can you verify that it builds and works even
if USB isn't compiled in, but the media core code is?
IOW, can you test the
CONFIG_USB=m
CONFIG_MEDIA_CONTROLLER=y
CONFIG_MEDIA_SUPPORT=y
case? Judging by your oops stack trace, I think you currently have
MEDIA_SUPPORT=m.
Also, I do wonder if we should move that #if to _outside_ the
function. Because inside the function, things will compile but
silently not work (like you found), if it is ever mis-used. Outside
that function, you'll get link-errors if you try to misuse that
function.
